Product Overview:

375nm Single Mode Laser Diode Source Module with Integrated Nichia NDU4116

These 375nm Scientific Series laser diode modules deliver excellent beam quality and very high stability in research laboratory environments. They offer low noise performance to produce a high signal to noise ratio for the most demanding R&D applications. These modules are offered in a self-contained high reliability enclosure which includes a LASORB power surge protection device. They offer user-adjustable power up to 70mW. These units are shipped fully calibrated & pre-tested with the matching current source and temperature controller as well as the required interface cables.

Factory Set Fail-Safe Laser Diode Protection Features

These units offer multiple layers of protection for the internal Nichia source. They have an integrated LASORB diode on the current supply board which offers a fail-safe clamp of the current / voltage to the integrated laser diode, and eliminate the possibility of power surges and ESD damaging the laser. These units also are configured with pre-set current and temperature limits. The bias current range is preset to prevent the possibility of over driving the laser source. The over-temperature shut down feature is 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 user sets the output power of the laser module via the controller unit.

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.
  • Fiber-Coupled Output *
    Fiber Patch Cable Output, order option –KVAFC. Single-mode fiber, with FC/UPC connector. Other options are available; click here to see options.
  • Benchtop Controller
    Benchtop Controller, Model LDC-405. Provides easy-to-use front panel interface and fiber output.

* 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.
