Femtosecond Mode-Locked Laser, Module (FML-15-M)

Data Sheet

Product Overview

The Optilab FML-15-M Femtosecond Mode-Locked Laser (FML) Module utilizes a proprietary Saturable Absorber (SA) for passive mode locking. It delivers femtosecond pulses with an excellent power stability and reliability. Designed with no moving parts, and requiring no polarization controller, the compact FML-15-M is built with highly qualified photonics components to provide operation life of 10+ year. The pulse width is factory selectable from 200 fs and up, with near transform-limited pulse shape and a better than 20 dB pedestal, and the pulse repetition rate can be specified from 10 to 50 MHz with either a polarization maintaining (PM) or single mode (SM) fiber output.
