Passively mode-locked performances of c-cut Nd:La0.05Lu0.95VO4 crystal

In the paper, passively mode-locked laser of c-cut Nd:La0.05Lu0.95VO4 crystal at 1.08 and 1.06μm were firstly demonstrated with a semiconductor saturable absorber mirror (SESAM). A simple and flexible method of selecting the mode-locking wavelength using a pair of prisms and a blade was applied. In 1.08μm band, two mode-locked laser states oscillating at 1084.8 nm and 1087.9 nm were obtained, respectively. In 1.06μm band, dual-wavelength mode-locking at 1065.3 nm and 1067.5 nm was achieved. Current results indicate that c-cut Nd:La0.05Lu0.95VO4 crystal could be a potential gain medium for helium optical pumping, as well as generation of terahertz (THz) radiations.
