Product Overview
1590nm, 15mW CW / 45mW (Pulse) DFB Laser Diode
The LD4B-1590-DFB-2.5G-15-COAXB-2-SM1-FA-CW-0.5 is an InGaAsP MQW laser diode with internal photodiode coupled to an optical fiber and packaged into a hermetic TO-case. This compact coaxial fiber-coupled DFB laser is mounted in a double-sided bracket to facilitate mounting and heat-sinking. The special feature of the LDS technology is the increased thermal stability of optical power.

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.
