1064nm 300mW 50ps SM Pulsed DFB Laser Diode

1064nm 300mW 50ps SM Pulsed DFB Laser Diode

This product offers a broad portfolio of high-power single-spatial-mode laser diodes, suitable for any wavelength within the 780nm to 1340nm range. It is available with a TO-9 (9mm) free-space light output package or a standard 14-pin butterfly package with fiber pigtail output (both single-mode and polarization-maintaining pigtails are optional). The polarization extinction ratio (PER) of laser diodes with polarization-maintaining (PM) pigtail output is typically >18dB. These fiber-coupled laser diodes can be configured for CW (up to 600mW) or pulsed operation, and are optionally available with fiber Bragg grating (FBG) versions for spectral stabilization. The pulsed laser diodes from Idealphotonics are specifically designed for seed source applications, featuring low-noise peak optical power up to 1.2W, and a broadened spectrum that suppresses stimulated Brillouin scattering (SBS) in high-power fiber lasers. Each laser diode product line undergoes a qualification program to demonstrate high reliability. All provided lasers pass individual screening procedures and are accompanied by detailed factory test reports.

5–Picosecond (gain switching) and nanosecond laser diode drivers can be ordered with the laser or separately

The light emitted by the device is invisible and may be harmful to the human eye. When the device is in operation, avoid looking directly at the fiber optic connector. When operating with the connector open, it is essential to wear appropriate laser safety glasses.

Absolute Max. ratings should only be applied to laser diodes for short periods of time. Prolonged exposure to Max. ratings or exposure to more than one Max. rating may cause damage to the device or affect its reliability. Operating a laser diode outside of the Max. rating may result in equipment failure or safety hazards

The power supply used with the part must be used to ensure that the Max. forward current is not exceeded

An appropriate heat sink needs to be provided for the laser diode on the heat sink. The laser diode must be mounted on the heat sink with 4 screws (tightened in an X-shaped manner, with an initial torque set to 0.075 Nm and a final X-bolt to 0.15 Nm) or a clamp. The deviation of the surface flatness of the radiator must be less than 0.05mm. It is recommended to use indium foil or thermally conductive soft material as a thermal interface between the bottom of the housing and the radiator. Hot grease is not desired

Avoid back reflections from laser diodes. It can have an impact on device performance in terms of spectrum and power stability. It can also lead to fatal laser diode end face damage. Optical isolators are highly recommended to block back reflections. Do not pull the fiber. Do not bend fibers with a radius of less than 3 cm.

Only the laser module can be operated with clean fiber optic connectors. If necessary, regularly inspect and clean the fittings. To clean the connector, only use a cleanroom-compatible paper towel, place some isopropyl alcohol on it and carefully clean the end face of the connector, or use a special fiber optic cleaning tool. Cleaning is carried out only with the laser current turned off.

Electrostatic discharge can cause equipment failure. Take the necessary precautions to prevent ESD.
