1550nm, 500mW HHL Laser Diode Overview
Fabry-Perot laser diode from Fibercom Ltd. The laser package is a high heat load (HHL) with an integrated TE cooler, thermistor and monitor photodiode. The TEC and thermistor provide stable wavelength and power operation over a wide temperature range of -20 to +40C. The integrated photodiode provides optical power feedback so that the user can operate the laser in an automatic power feedback mode of operation. These multimode devices offer and output power up to 500 mW at a center wavelength of 1550nm.
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.
