I then created a basic TTL laser driver circuit using some veroboard, the required components and such. Now I tested the circuit with a few high power LEDs. It worked. I connected the laser diode...

    Laser Diodes reuse to work with my circuit?

    Okay so I have created a Daedel driver circuit for my laser diode which s currently an 808nM 300mW IR diode. Now before i tested my diode i tried some LEDs in its place. I connected 2 1.5v LEDs in series, thus drawing 3v the same as what my laser diode needs. Now the LEDs work absolutely fine...
