Hi, I am currently having difficulty in having a extremely stable (without fluctuation) diode output excitation source.

The laser I got is biased with voltage and it has lots of fluctuation. Mainly due to temperature??

I heard that if the laser diode is biased with current, then this problem would be gone. (temperature insenstive in some degree).

What are the control variable to tune the finest laser diode (monochromatic) output?

Any commericially avaible diode output source is fine....


Thanks,

Best,
BEE
