The 500B Series Laser Diode Drivers offer all the performance of the most advanced drivers for a fraction of the price. All models are quiet and stable enough for use in the most demanding applications such as spectroscopy and fiber optic communications.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 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 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.Our Model 300B Temperature Controllers and our complete line of Temperature Controlled Mounts and Telecom Mounts for laser diodes complement Newport 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.
Note that Models 501B and 525B are phased out and replaced by 505B and 560B , respectively.
