Diode lasers are going to have a range of power that they will operate at. Below the minium range they may "Go LED", which means, they emit light, but will not lase. The maxium power is due to COD, "Catastrophic Optical Damage", or heat disapation, or both. If you are doing research you should...

TE == transverse electric. It's one of the two possible polarizations for these type of diodes. The other being transverse magnetic. Can't really say on the price. Others here will chime in on that. I know that the price varies a lot by the quality for the 808nm diodes. Depending on what you...

Yes I was planning to operate the system as a pulse. I mentioned a 5 millisecond pulse at the end of my post. Pulsing a diode array is fairly easy, depending on how you construct it. LEDs have rise times in the nano-second range, so millisecond pulses are no problem. ( Often times running at...

Ahh. The musings. Beyond the goal of getting a Ruby laser operational are some experiments. I've noticed in the last year that very small, quite high power 405nm and 550nm LEDs ( not laser diodes ) have become available. These LEDs are capable of 60 lm/watt for the blue, and 120 lm/watt for...

Hi! I've reading the forum for a while now, learning all your tips, tricks, secrets. ha. I'm really interested in expanding my electronics hobbiest knowledge and getting into some lasers. I am interested in building a classic Ruby laser. ( Or at least mess around with the crystal right?) I...

Hi Everyone! I've been lurking around for a few weeks now, reading so much great stuff on here. I found the forum searching for information about Ruby Lasers. I'm a software engineer with a fair amount of electronics design knowledge. I'm interested in possibly building a classic Ruby laser. (...
