Product Overview:

637nm High Stability Red DPSS Laser Module Features

These precision laser diode modules employ diode-pumped solid state laser at 637nm, and the output power can be adjusted up to 170 mW. These highly stable sources are ideal for scientific laboratory applications requiring long term power stability and high beam quality. These units are shipped calibrated & tested with the matching current source and temperature controller as well as the required interface cables.

Laser Diode Protection Features

These units offer multiple layers of protection for the internal source: an integrated LASORB diode on the current supply board offers a fail-safe clamp of the current / voltage to the integrated laser diode; pre-set current and temperature limits. The LASORB was designed to eliminate the possibility of power surges and ESD damaging the laser.

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.

Adjustable Output Power

These units are shipped fully calibrated & pre-tested with the matching current source and temperature controller, as well as the required interface cables. The OEM controller unit allows the user to set the output power of the laser module.

Versatile Options Reduce Integration Time

The laser diode module can be ordered with options that save you time and effort, and increase the operational flexibility of the module. Inquire for more information about these options, pricing, and delivery.
  • Fiber Patch Cable Output, Option KVAFC. Different fiber types to choose from, multiple connector options.
  • Benchtop Controller, Model LDC-405. Provides easy-to-use front panel interface with display.

* POWER LOSS ASSOCIATED WITH FIBER-COUPLED OUTPUT: Please note that when a free-space laser diode is coupled to fiber there is some loss associated with the collimating lens employed in the coupling of the light. There is also power loss associated with the fiber coupler assembly and with the fiber patch cable. The LDX laser system has power loss associated with the fiber-coupling of the output of approximately 15 to 20% of the total power.
