495 nm, 20 mW Fabry-Perot Laser Diode, Coaxial Package, Polarization Maintaining Fiber-Coupled Overview
This laser is offered in a polarization maintaining fiber-coupled package and terminated with an FC/APC connector. The TO-can packaged 495 nm laser is mounted into a coaxial header and precisely coupled to the fiber pigtail output. The coaxial package is installed in a mounting bracket that also serves as an additional layer of heat sinking to keep the integrated source thermally stabilized. The mounting bracket allows the user to bolt the package to a heat sink to dissipate waste heat away from the internal laser diode. The fiber pigtail has a 900 micron loose tube jacket to allow the user to position the fiber without damaging the PM fiber. Other fiber and connector options are available; inquire for options and details.
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.
