Product Overview:

High Power 520nm Fiber-Coupled Laser Diode

These high power 520 nm laser diodes are offered in a multimode fiber-coupled HHL package. The laser package includes an integrated monitor photodiode, thermoelectric / TE cooler and thermistor in an industry standard 9-pin package. The fiber pigtail is a 105 μm core multimode fiber, NA 0.22, which is terminated with an FC/APC connector. Other fiber and connector options are available; inquire for options and details.

Proven Laser Diode Expertise

These high stability fiber coupled laser diodes are designed and manufactured to meet the most demanding R&D and industrial applications. Proprietary design, packaging, and fiber coupling processes produce laser diodes with very high stability and low noise. Extensive testing and burn-in before shipment ensures every laser diode meets the highest quality standards and will provide long-term reliability.

Important Notes on Operating Laser Diodes:

Electrical Operation: Operating a laser diode above the maximum ratings shown on the data sheet even for very short periods of time can damage the laser diode or reduce its lifetime. They should be electrically biased with a "laser diode driver" class current supply with low electrical noise and protection against voltage and current surges. Laser diodes are very sensitive to electrostatic discharge (ESD). Proper ESD precautions must be taken.

Mounting and Temperature Control: In order to maintain the lifetime of a laser diode, proper heat management is essential. Due to the design of the laser diode, heat is typically dissipated only through the base plate of the diode‘s package. A proper heat conducting interconnection between the diodes base plate and the heat sink must be maintained. Some devices require the use of a thermo-electric temperature controller (TEC controller) to remove the heat from the laser and stabilize the temperature.
