Product Overview:

1300nm, 10mW Quantum Dot Laser Diode

The QLF1335-AD is 1300 nm quantum dot laser diode device for use in extremely high temperature environment. The laser is mounted into a TO-56 header including a monitor PD for optical power control, and hermetic-sealed with a lens cap. Since quantum dot technologies are equipped with active layers of the device, it delivers excellent temperature characteristics and low power consumption.

- 1300 nm Quantum Dot Fabry-Perot Laser Diode
- Wide temperature operation: -25°C to 150°C
- 5.6mm TO-CAN package

Applications
- High temperature use
- Telecommunications

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.
