Pinout JDS Uniphase Laser Power Supply

Don't apologise for your English, it's far better than many native English speakers' that I've read! The connections you need to make are: Pin 1 to pin 3 (interlock) Pin 13 to pin 2 (laser on) Current control signal to pin 6; put a 1K potentiometer between pin 11 (0V) and pin 13 (15V internal supply) with the wiper to pin 6 OR use an external

0 to 15V supply to pin 6 grounded to pin 11. Light control signal to pin 7; put a 1K potentiometer between pin 11 (0V) and pin 13 (15V internal supply) with the wiper to pin 7 OR use an external 0 to 15V supply to pin 7 grounded to pin 11. To select current control mode, put a link between pin 22 and 5; leave the link out for power (light) control mode. Pins 10,11,14,20,21,22 & 24 are all connected to 0V Pin 8 is the power monitor pin, the scaling depends on the exact version of laser head you have connected. Pin 9 is the current monitor pin, scaling is 0.1V / Amp. Hope that helps. By the way, you may want to visit the alt.lasers group as you may find lots of useful information on there. Martin

But if it doesn't start all the time, could be something else wrong.

Hi Martin,

Many thanks for your help and the encouraged words. I'm now able to monitor the signal from the electronic and also test the power supply stand alone.

By the way: the Laser head is a 2211-65MLQYV

Many Thanks
