To the best of our knowledge,this is the first time that a mid-infrared Er^(3+):CaF_(2)-SrF_(2) laser has achieved continuous-wave mode-locked operation by a semiconductor saturable absorber mirror.The laser emits a m...

Optical waveguides are fabricated in Nd3^+:y3^+:SrF2 crystals by a 1-kHz femtosecond laser using the double-line approach. Waveguides with different separations (10, 15, and 20 μm) between two consecutive opt...
