Hello All! I am working on a scanning experiment, and had a question about using lasers to find the location of the specimen inside the scanning head. I was planning to use two lasers, which would project a laser grid onto both sides of the sample, from both sides of the main optical train...

Hello! I'm working on a retinal projector that uses a RGB laser system. Of course, I will be testing the rig extensively and have safeguards implemented before applying for authorization to test it on humans. I have a question pertaining to the dimensions of the Aixiz modules for 3.8mm...

Greetings. I am looking for a source of low price 532nm laser pointers/ seld-contained modules. The power must be <1mW, and they must be filtered for 808 and 1064nm. I am looking to buy 200 of these, and have checked out dealextreme, o-like and Tmart. The problem was that none of them...

Greetings to All. Just wanted to throw this out there, in case someone has such a beast lying around. I am looking for a mechanical vacuum pump capable of reaching 10 microns and below (used, of course). For this cause, I offer 150 eu, which is 200 dollars exactly. Also looking for a vacuum...

Greetings. My problem is thus: I own a 60mw 405 Labby (self-made) and a chinese 50mw (true power) greenie. Googling the laser laws gave no results. I have no access to legal databases and have not the slightest idea about how to research such a subject. Can someone point the way to find laser...

From what I have read, the frequency doubling mechanism is pretty intricate in these devices, and is based on a raman transition. Could someone explain the science behind these lasers?

Greetings. On a side note to my laser hobby, I would like to purchace a 20mw labby on behalf of my brother, for use as a laser show. It will be running 24/7, so it needs to have a good mttf rating. The only cap is the price: it needs to be less than 150 euro. Does anyone have some information...

Greetings to All. I have recently scored two drives on the flea market for 5 euro apiece. One is a CD writer (can read dvd's) and one is a 12x dvd writer (!!). I plan to use the optical sled from the 12x in conjunction with A lm317 driver to form a factory-collimated labby of sorts. Because of...
