By Constant Power Modes and Mod Input


The LDD P Series of laser diode drivers come in three compact models to work with all laser diode / photodiode confi gurations. Each model is available in 200mA and 400mA versions to best fi t your laser diode requirements. When it is essential to have high performance in your application, these low noise drivers offer excellent current stability in constant current mode or <0.02% power stability in constant power mode. Precisely control the laser diode or photodiode setpoint current with the on-board Output Current Adjust trimpot or via a remote voltage to the modulation input. The modulation input’s small signal 3 dB bandwidth is DC to 2 MHz in constant current mode and dependent on photodiode speed in constant power mode. Measure laser diode and photodiode current from two buffered monitor outputs
