Pulsed laser module

nanosecondfiberfiber optic

Product Description
This is a 1550 nm narrow-linewidth pulsed fiber laser designed with eye-safety considerations. The module uses a MOPA (Master Oscillator Power Amplifier) architecture with a DFB semiconductor laser as the seed source. The optimized amplifier stage produces kilowatt-level peak power with nanosecond pulse widths. A monitoring output is integrated. The unit is intended as an emission source for solid-state LiDAR and for industrial fiber-optic sensing and free-space optical links.

Application

• Fiber optic sensing
• Free-space optical communication
• LiDAR (solid-state)

Features

• Kilowatt-level peak power (pulsed)
• High electro-optical conversion efficiency
• Designed for stable operation and reliable monitoring
