Orthogonally dual-polarization passively mode-locking operation of Nd:La0.25Gd0.75VO4 crystal

Two-photon absorption in La0.05Gd0.95VO4 crystal at 523 nm under irradiation with picosecond pulses

“…Mixed vanadate crystals were proposed for the development of a laser matrix with a disordered structure for broadening laser bands and generating shorter laser pulses [12][13][14][15]. Unlike most vanadates, LaVO4 crystal has a monoclinic structure, so even small doping of La in the mixed vanadate LaxGd1-xVO4 can led to a strong disordering of its structure.…”

“…In spite the reduction of the emission crosssection of Nd ions in mixed vanadate it stays larger than that in YAG crystal, and LaxGd1-xVO4 remains perspective for developing short pulse solid-state laser. Xu et al received pulses with a duration of 2.2 ps from the Nd:La0.25Gd0.75VO4 laser with a SESAM, which is the shortest value obtained using Nd-doped vanadate crystals [14]. Diode-pumped microchip laser with a passive Q-switch Cr 4+ :YAG emits laser pulses with the duration of 0.8 ns [15].…”
