Dear All,
I am looking for a good software for drawing optics scheme(see examples below). I am wondering whether there is a software specially designed for this purpose. Whole my academic life, I was drawing optics schemes in Microsoft Word, Powerpoint and Coral Draw.
Examples:
If you will take a magnet and a small piece of iron,for example. Then you may put the piece of iron on a table and try to pick it up by your magnet. Eventually, you will be able to change the position of the piece by lifting in up. At first glance, it seems that you magnetic field did some work...
Do you mean that op-amp attempts to make not always makes the voltage difference between the inputs zero?
Golden rules:
I. The output attempts to do whatever is necessary to make the voltage difference between the inputs zero.
II. The inputs draw no current.
Hello
I need to do some simulations before trying to make a real circuit. I was advised to use the free software by Linear Technology. However, it works bad.
I have a circuit with a couple of operational amplifiers(op-amp). According to the first golden rule, an op-amp should keep equal...
Hello all,
I am a graduate Physics student. I have strong math background. However, I started to forget some formulas, equations and so on because I am more focused on experimental physics.
I am looking for a book in math that I can you as a handbook. What do you think about Mathematical...
Laser on YAG Nd+3 does not have a lot with electronics. It will be totally optics project. You will only need some power supply unit. Everything else will be in optics - lenses, active region, optical pumping and so on.
You will have great troubles to make your laser generate laser light.
1) In general, it is true. However, you need to be more careful. There are a lot of different glasses. Regular glass is based on SiO2. We can added some metals and it will have different colors. Please, check this...
@martin1512: mmm. You will no be able to create 1W laser at home without proper education. Also, Laser with 1W of output power is VERY! dangerous for eyes. I do not recommend you to do such experiments at home without proper defense. Sorry, due to yours safety I will not help you.
From Wiki...
You can buy cheap one then disassemble it. After it, You can use YAG glass as active region and with proper cooling and pumping you will be able to increase output power.
You can buy http://www.calibex.com/ND3-laser/zzcalibex1zB1z0--search-html?nxtg=2bb70a280518-CCB6C1F753DAB9A8
then create based on YAG glass more powerful laser.
You can buy 100 diode lasers(5mW each)and make an array. If you will be able to phased them... you will receive 2x100x5mw = 1W of power. However you will have to make good cooling system for continuous laser.
I advise you to buy YAG:Nd+3 glass(http://en.wikipedia.org/wiki/Nd:YAG_laser), two...
