hi blrock, Cool to see some other SA people on here.. I just finished studying engineering, yay..., and my budget is getting better (usually scrounged around for blu ray diodes, and greens, and hacked DVD roms at the University for reds), I worked at the National laser centre for a bit in...

I am currently working on modifying an existing Confocal LSM (Laser scanning microscope) into a 2 photon system, The setup i am modifying is a Zeiss LSM-410, But its still an ongoing project. and i get to play with this : Femtosecond laser

Would one be able to use a normal LM317 driver to drive the DPSS Green laser, like you drive a Bluray or Red ?

cool, We have some scopes in the lab.. will do that :P Thanx

From the green DPSS laser topic I have redone the circuit with a MOSFET... I will have to wait for my diodes to arrive before I will be able to test it.., R,G,V on their way... Any comments welcome.. :P Once I get all this working I will post the full circuit diagrams and pcb layouts I...

I think I should reply in THIS topic, might suit the topic more.. , R G V lasers.. :P

I am also thinking of modulating diodes for colour mixing, would pulsing the current damage the diode ? as in this circuit ? This is to be used for the R,G and V laser diodes, Is there any different driving methods that I need to use for a green diode (actually a DPSS 50mW green , removed...

Is it possible to change the pump Diode (with one from a DVD burner) of my 5mW green ? (this is an ebay thingy.. Something I won't feel Too bad about killing, but killing it will be sad still) And also, How would I be able to PWM my green laser (i cannot just PWM the driver power supply , as...
