ABSTRACT
We report on the continuous-wave (CW) and, for what we believe to be the first time, passively mode-locked (ML) laser operation of an Yb3+-doped YSr3(PO4)3 crystal. Utilizing a 976-nm spatially single-mode, fiber-coupled laser diode as pump source, the YbYSr3(PO4)3 laser delivers a maximum CW output power of 333â
mW at 1045.8â
nm with an optical efficiency of 55.7% and a slope efficiency of 60.9%. Employing a quartz-based Lyot filter, an impressive wavelength tuning range of 97â
nm at the zero level was achieved in the CW regime, spanning from 1007â
nm to 1104â
nm. In the ML regime, incorporating a commercially available semiconductor saturable absorber mirror (SESAM) to initiate and maintain soliton-like pulse shaping, the YbYSr3(PO4)3 laser generated pulses as short as 61 fs at 1062.7â
nm, with an average output power of 38â
mW at a repetition rate of â¼66.7â
MHz.
