375nm, Fiber-Coupled Nichia NDU7216E Source Laser Module
These 375nm Scientific Series fiber-coupled laser diode modules were designed to deliver very high stability in research laboratory environments. They are a plug and play source and control solution which include a Nichia NDU7216E laser diode mounted into a compact thermally stabilized head, with a fiber-coupled output. Inquire for the single-mode fiber and connector options available.
These units are shipped fully calibrated & pre-tested with the matching current source and temperature controller as well as the required interface cables. They offer excellent beam quality and low noise performance to produce a high signal to noise ratio for the most demanding R&D applications.
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 power surge clamp to protect the integrated laser diode. The laser diode drive current range is pre-set 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.
Optional Benchtop Controller
The Benchtop Controller, Model LDC-405, is available for applications where intuitive front-panel control of the laser module is beneficial to the application. The benchtop controller provides easy adjustment of the output power, and the wavelength can be fine-tuned using the temperature controller.
* POWER LOSS ASSOCIATED WITH FIBER-COUPLED OUTPUT:
The total power out of the Nichia source laser in the LDX series module is typically 200mW. However, 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. With Nichia source laser diodes, there is a typical efficiency in the range of 80 to 90% for their 375nm wavelength lasers. The LDX laser system has power loss associated with the fiber-coupling of the output of approximately 15 to 20% of the total power. This loss is due to loss in the fiber of approximately 9% due to absorption and a small amount of inherent reflection. The output collimator contributes an additional 10% to total power loss. If the customer will only use the system with the fiber-coupled output, then we recommend that we remove the output collimator from the laser head so there will be > 175mW out of the fiber (exiting the fiber). If the customer must have the collimator in the laser head for a free-space beam, then the output power maximum is approximately 160mW maximum. Please discuss options with the sales engineer prior to order placement.
