1560nm Sub-picosecond Pulsed Fiber Laser

Connet 1560nm sub-picosecond pulsed fiber laser adopts the all-fiber design and is an all PM fiber laser based on SESAM passive mode-locked technology. The stable linearly-polarized femtosecond laser output can be achieved through the optimized optical path, which is highly reliable and maintenance-free.

Features:
• SAM passive mode-locked all PM fiber design
• Robust and Compact
• Sub-picosecond pulse width, MHz repetition rate
• Low amplitude noise
• Maintenance-free operation

Applications:
• Seed laser for fiber laser or fiber amplifier
• Time precision detection
• Test and measurement
• R&D
• LIDAR
