Laser Diode Power Supply With TTL Blanking

 

CURRENT--->Laser Diode constant current @ 1A max. with TTL blanking via PC-Port.

1st.  LM317 voltage current

2nd. LM317 constant current

Mos-FET  TTL blanking.

CNY-7 Optocoupler for galvanically separated connection.

LASERHEAD--->  Pusch DPSS Laser with 5mW output ,,, but IR Laserdiode has changed, now a 1W 808nm LD

work well @ about 700mW IR.
