1550nm, 500 mW, Fabry-Perot Laser Diode Overview
These 1550nm laser diodes offer output power up to 500mW. They are packaged in a TO-3 style TO-can and are based on a Fabry-Perot laser structure. They have an integrated photo-diode. The are manufactured and sold by Fibercom and fulfilled worldwide through Laser Lab Source.
These multimode lasers have a typical spectral width of 3.5 nanometers. They are designed to be operate in a CW mode. The laser emitter size is specified at 100 micron x 1 micron and the TO-3 package includes an MPD with an output current range of 1 to 1000 microamps. The specified maximum for the MPD reverse voltage is nine volts. These 1550nm lasers are specified with a wavelength tuning derivative of approximately three nanometers per shift in temperature of one degree Celsius.
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.
