Complete Laser Diode Control Solutions
Our diode temperature controllers and our complete line of laser diode mounts complement the 500B Series Drivers in performance and value. When it comes to selecting a laser diode mount and temperature controller to go along with your new driver Newport does all the work for you. Our newly introduced laser diode control kit (LDKIT series) bundles the diode driver, temperature controller, mount, cables and thermal paste compound all at a great price.
Constant Current or Constant Power Control
Intuitive front panel controls make these instruments extremely simple to use. There are two operating modes: constant current or constant power. Dual current-level selection lets you optimize current resolution settings by precisely varying the output to the laser diode.
Comprehensive Laser Diode Safety Features
Comprehensive laser diode safety features are built into every 500B Series Laser Diode Driver. Redundant FET and relay shorting circuits protect the laser diode at the beginning of the slow turn-on sequence. After a short delay, the output current slowly ramps to your preset operating level. The current limit setting is fully independent.
External Analog Modulation
External analog modulation allows you to voltage control or modulate the output. In the high bandwidth mode, you can modulate the laser up to 800 kHz. For precision laser output power control, or wavelength tuning with external control circuitry, you can slowly modulate the laser output in the low bandwidth mode and maintain low noise operation.
Additional 500B Features and Benefits
A monitor photodiode can be reverse-biased from 0–5 V with no external power supply, Preset output current or laser power level. USB 2.0 interface for remote control, Fully independent current limit
