488nm, 200mW Single Mode Laser Diode Source with Power Supply & Cooled Housing

Product Overview:

Designed for a wide range of research and scientific applications, these 488nm laser diodes modules are offered in a self-contained enclosure and deliver user adjustable power up to 200mW. These Scientific Series lasers offer excellent power stability, beam structure, and pointing stability. They can be purchased with an integrated OEM power supply or with a fully integrated bench-top controller with front panel interface.

Turn-Key Performance:
The emitter source of these units is an integrated sky blue gallium nitride laser diode from Nichia. These units precisely control the bias current and temperature of the laser. They include a LASORB protection component which offers the highest level of ESD and transient protection. The laser source is a TO-can which is mounted into a 5.6mm socket that is actively cooled to 25 degrees C. The TO-can socket and laser are enclosed in an anodized aluminum housing. These units are designed to run in continuous wave mode. The bias current range is preset to prevent the possibility of over driving the laser source and the unit has an over-temperature shut down feature based on feedback from a sensor located against the laser package header.

Pre-Configured Power Supply and Cooling System:
These modules ship with a pre-configured power supply that has a maximum current range limit within the safety ratings of the laser. The user has the ability to adjust the amplitude of the bias current and adjust the laser output power in a linear fashion. A separate 5 VDC power supply is used as an input to the current controller to set the bias point and adjust the optical output power. The pre-set limits in the controller unit will not allow the user to over-drive the Nichia 488nm source.
