The C-band and 1 µm narrow spectrum bandwidth ultrafast fiber laser (FPLNB) is a passively mode-locked fiber laser that utilizes a saturable absorber to deliver a narrow spectral bandwidth of less than 0.1nm.
The FPLNB laser has excellent stability and reliability with turnkey operation. The wavelength is factory selectable throughout C-band or 1 µm band. The pulse width can be up to 100ps with near transform-limited pulse shape and a better than -20 dB pedestal. The timing jitter is as low as 100 fs. The repetition rate can be specified from 10 to 100 MHz with either a polarization-maintaining (PM) or non-PM fiber output. With up to 5 mW output power, the FPLNB series is an ideal narrow bandwidth source for seeding applications. An RF synchronization output is provided as a trigger signal. A 780 nm band option is also available.
