| Abstract: | With a fiber coupled laser diode array as the pump source, Nd-doped Lu2SiO5 (Nd:LSO) crystal lasers at 4F3/2→4I11/2 and 4F3/2→4I13/2 transitions were demonstrated. The active Q-switched dual-wavelength lasers at about 1.08 μm, as well as continuous-wave
(CW) and active Q-switched lasers at 1357 nm are reported for the first time, to the best of our knowledge. Considering the
small emission cross-sections and long fluorescence lifetime, this material possesses large energy storage ability and excellent
Q-switched properties. The special emission wavelength at 1357 nm will have promising applications to be used in many fields,
such as THz generation, pumping of Cr3+:LiSAF, repumping of strontium optical clock, laser Doppler velocimeter and distributed fiber sensor. |
