About this book
A textbook on lasers and optical engineering should include all aspects of lasers and optics; however, this is a large undertaking. The objective of this book is to give an introduction to the subject on a level such that under graduate students (mostly juniors/seniors), from disciplines like electrical engineering, physics, and optical engineering, can use the book. To achieve this goal, a lot of basic background material, central to the subject, has been covered in optics and laser physics. Students with an elementary knowledge of freshman physics and with no formal courses in electromagnetic theory should be able to follow the book, although for some sections, knowledge of electromagnetic theory, the Fourier transform, and linear systems would be highly beneficial. There are excellent books on optics, laser physics, and optical engineering. Actually, most of my knowledge was acquired through these. However, when I started teaching an undergraduate course in 1974, under the same heading as the title of this book, I had to use four books to cover the material I thought an electrical engineer needed for his introduction to the world of lasers and optical engineering. In my sabbatical year, 1980-1981, I started writing class notes for my students, so that they could get through the course by possibly buying only one book. Eventually, these notes grew with the help of my undergraduate and graduate students, and the final result is this book.

    Works well

    After reading other reviews, it seemed like a good idea to test this device here at home before relying on it overseas. This is easy to do if you have access to 240v at home, but you may want someone familiar with electrical devices to help.Since some reviews mentioned heating as an issue, I tried it with no load for half an hour, observing only 10 degrees increase in temperature. Next was a 40 watts light bulb as the load, then 75 watts, then 100 watts. At 100 watts, the outside case warmed up to 161 degrees after an hour, which isn't too bad. However, the temperature never really stabilized, indicating that heat buildup could be an issue if running near the full rated load (200 watts), especially for extended times. I don't think it would be a problem with less than 50 watts or so of load.I took the case apart and found it had no ventilation holes to allow the heat to escape. If you are running near the full rated load, you may want to open the case (with the... 5/5 Jhs (USA) - See all my reviews Verified Purchase(What's this?)

    Simran SMF-200, works well for select purposes.

    "Simran SMF-200 Deluxe 200 Watts Step Down Voltage Converter for International Travel to AC 220V/240V Countries". I bought this product for a trip to Spain, needed to run my laptops and to recharge phone, camera, laptop batteries, etc.Note that the power supply for my laptop is rated as having a 120-240V input. Many power supply "bricks" are thus rated, in principle letting them plug directly into a 240 volt supply (Spain). Thus in theory, I could have plugged my laptop directly into the Spanish outlets. However, reality does not always respect theory, so despite its nominal 120-240V input, I had concerns about my power supply overheating or burning out if I plugged directly into the Spanish receptacles. So instead, I plugged the Simran SMF-200 into the 240V wall, then my laptop power supply into the SMF-200, knowing that if anything blew out, it would be the SMF-200 converter, but my laptop and its adapter would be safe. Some of my other devices,... 4/5 Marc Gottlieb (Scottsdale, AZ USA) - See all my reviews, May 11, 2015

This review is from: Simran SMF-200 Deluxe 200 Watts Step Down Voltage Converter for International Travel to 220V Countries Ideal for Laptops, Cameras, Phones, iPads etc (Personal Computers) I have used this device on four separate European vacations and so far, so good. I bought as part of a bundle which included a small power strip and an adapter. I use is to recharge my camera batteries, phone and power my laptop. I try not leave it plug in all night because I do worry about overheating (though this has not been an issue at anytime). Packing for my fifth trip now and this item is a must in my bag. The only true complaint is the bulkiness and the weight. Other than that - no problems at all at this point. I do recommend this product if using small electronics. I don't think it works for hair dryers and things of that nature. Help other customers find the most helpful reviews  Was this review helpful to you? , February 17, 2017

(Electronics) I'm using this item even as I type this review. I'm from the United States (110VAC) and currently traveling in Europe (220VAC). Most of my devices can handle 110V or 220V and I would need only the plug adapter (rearranging the metal prongs but not changing the voltage). This device handles the remainder of my devices that are (only) 110VAC, as well as those that handle 220VAC as well as USB charging. It's operation is nearly silent and generates just a bit of heat. I was thinking that it generated electrical noise into the devices being charged when (for example) you had headphones plugged into a phone or laptop. However, I'm wondering if it's inherent in the devices (seeing a different voltage and different frequency) and not a "fault" of the voltage converter. Regardless, this does exactly what I wanted.

This review is from: KRIËGER 1150 Watt Voltage Transformer 120V to from 230V AC outlet American European Step up down Converter 50 60 Hz outlets with 2.1A USB includes IEC German Schuko Nema 5-15P cord connection MET certified approved under UL CSA ULT1150 (Electronics) I took it to the UK and used it for charging my phone, razor, camera batteries etc. (no hair driers or curlers). It was silent and did the job, it also has a 240v pass through so when you plug it in to a UK socket you still have a socket available on the unit. This proved to be quite useful since in the three hotels I stayed at the hot water kettle or light plugs into the only socket on the counter, this allowed the unit to be on and use the socket. Note you have to buy the UK plug adapter. Help other customers find the most helpful reviews  Was this review helpful to you? , October 13, 2016

    THE STU-500 IS ACTUALLY AN ( AUTO-TRANSFORMER ) NOT AN ISOLATION TRANSFORMER

    THE STU-500 STEP UP AND DOWN VOLTAGE CONVERTER---IS ACTUALLY AN ( AUTO-TRANSFORMER ) NOT AN ISOLATION TRANSFORMER. AN AUTO-TRANSFORMER IS ACTUALLY AN ELECTRICAL TRANSFORMER WITH ONLY ONE WINDING ON THE MAIN CORE, WITH MULTIPLE TAPS. I WAS INITALLY LOOKING FOR A 120VAC TO 240VAC STEP UP ISOLATION TRANSFORMER, AFTER LOOKING AT ALL THE NEG REVIEWS AND COMPLAINTS ABOUT MEASURING RESISTANCE BETWEEN THE PRIMARY INPUT PLUG AND THE OUTPUT RECEPTACLES, I SUSPECTED IT WAS AN AUTO-TRANS AND SINCE THE PRICE WAS RIGHT, I PURCHASED IT, WHEN IT ARRIVED, I DID NOT APPLY POWER TO IT. I SIMPLY TOOK IT APART, AND STARTED TRACING THE WIRES INTERNALLY, AND SURE ENOUGH IT TRACED OUT TO BE AN AUTO-TRANS DEVICE. AN AUTO-TRANS DOES NOT PROVIDE ELECTRICAL ISOLATION BETWEEN IT'S WINDINGS AS AN ORDINARY TRANS DOES. A FAILURE OF THE ISOLATION OF THE INTERNAL WINDINGS CAN RESULT IN HIGHER THAN NORMAL VOLTAGES.

    Goldsource STU-3000

    The transformer works as specified. I tested it at 1440 watts load with 208 VAC input, the load being 1240 watts at 120 VAC and 200 watts at 220 VAC. The transformers temperature rise was reasonalby, although the iron laminations don't seem big enough for 3KW. I opened the unit up, and was horrified! The product is labeled as CE marked and manufactured to ISO9001. I frankly don't believe it! There was hot glue holding many of the parts to the panels, the soldering was of poor quality, with burn marks on the wires, and wires soldered to the boards and connectors with being mechanically attached, just the solder keeps the wire in place. This does not meet standard. The power cord is 16 AWG wire, which at 220 VAC input is OK, but 120 VAC with a 30 amp fuse is undersize by at least 2 wire gauges. The plug is also only rated at 15 amps, so there is no way to get 3 KW out of this transformer with 120 VAC input on a houselhold outlet. It could deliver 3 KW with a 220 VAC input.

    5/5 3ternalist (USA) - See all my reviews Verified Purchase(What's this?) This review is from: Goldsource STU-500 Voltage Converter: AC 110V / 220V 500W Step-up and Step-down AC Voltage Transformer with 5V USB Port - Maximum Load Capacity (MLC): 500 Watts (Electronics) Moved to Europe 5 months ago and this converter has worked perfectly with our US television. We use the tv as a computer monitor and it is flawless. There is a small hum, but hardly noticeable when watching or listening to something. I purchased the 500 watt converter for my 275 watt TV...this was a wise choice and the seller even told me that you should get a wattage converter that is double the amount that you wish to convert. I assume this helps with the noise level and variation in electronics products.I am also happy with this purchase because now if I really wanted to I can take me EU electonics back to the US and step-down the wattage...although I will probably sell most gadgets that do not have a range of acceptable voltage., June 4, 2016
