Constant current is just what it states a constant output level over time say 30 ma in theory forever if needed. For the driving of the laser diodes ld special drivers circuits are used. At a very general level there are a few classes or types of laser drivers which you will hear commonly discussed. This capacitor is used to filtering high frequency noise from our dc source and gives to input pin3 of the lm317 voltage regulator ic.

Working of laser diode driver circuit. Here is a great video on how to make a laser diode driver. 1 produce constant regulated voltage. Constant current cw pulsing including qcw low power and high power drivers.

2 produce constant current driven through the ld load. As battery start giving supply it first flow through the ceramic capacitor 0 1uf. The potentiometer 10k and resistor are used as the voltage limiting circuit connected with the adjustable pin1.
