We extend the use of a saturable Bragg reflector to modelock a NaCl:OH- color center laser, producing pulses adjustable from 200 fs to 2 ps, and tunable from 1. 499 µm to 1. 535 µm, with the minimum pulsewidth near 1. 51 µm. The laser is self-starting, requires no dedicated dispersion compensating optics, and maintains a highly stable, nearly transform limited output pulse train with up to 150 mW average output power.
