NACL-OH- COLOR-CENTER LASER MODELOCKED BY A NOVEL BONDED SATURABLE BRAGG REFLECTOR

We present the design and modelocking results of a novel saturable Bra gg reflector constructed fi om separate Bragg stack and quantum well s emiconductor wafers, bonded by the technique of atomic rearrangement. This device was used to modelock a NaCl:OH- color center laser, produc ing 200 fs pulses in the 1.60 mu m range. 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 500 mW average output power.
