Abstract:
A compact, passively Q-switched fiber laser with a tunable output is demonstrated. The proposed system uses a short length ytterbium doped fiber to create a very stable and compact optical circuit that uses black phosphorus (BP) as a saturable absorber to generate the desired short pulses. A stable Q-switch pulse train is obtained, with an operational wavelength range from 1056.6–1083.3 nm. Concurrently, a maximum pulse energy and minimum pulse width as well as a repetition rate range of 7.1 nJ, 4 µs and 6.0–44.8 kHz...

The YDF is then joined to a polarization insensitive isolator and subsequently connected to an Agiltron Inc., FOTF-023120323 TBPF. The TBPF serves to filter and stabilize the lasing wavelength...
