Viesturs, it seems to me that your laser diode is just acting as a "normal" LED, not as a laser. This state is only achieved at a very distinct point up on top of the voltage/current curve. The laser diode supply electronics must take care of this which is a rather delicate controlling task. In other words, the producer of that electronics thing is responsible for keeping the correct working point. Mostly there isn't much to adjust on them. Are you sure you are using the correct supply voltage as specified? If this certain voltage is not reached, the diode will not be brought up to the laser point, if it is too high, the diode could soon release its magic smoke.
