Continuous-wave laser diodes in precision-instrument applications require constant-current sources to drive them. Proper design of such a driver must involve careful tackling of robustness, stability, ...

I laser = (5V – V laser) / (R1 + R ds-sat) where R ds-sat = 25 mΩ and V laser = 2.0 V Values for both R ds-sat and V laser were taken from the datasheets of Q1 and the laser diode, respectively ...

You can maintain excellent stability in both Constant Current and Constant Power mode. The PLD-CH Series supports all laser diode / photodiode pin configurations. The 12.5 A model has a 50 kHz ...

Product description - uniLDD is a DC input power converter designed to supply CW up to 100A current or pulsed (QCW) up to 360A for the single emitter, bar, stacked laser diode, or high power VCSEL in ...

The Design Challenge In low power laser diode modules the designer has the option to use the classical discrete solution or take advantage of fully integrated driver ICs. Often the component cost is ...
