“…For example, the heat capacity and conductivity of Nd:YAG are 0.59 J/(g·K) and 0.13 W/(cm·K), respectively; however, as for Nd:YVO4 are corresponding to 0.79 J/(g·K) and 0.06 W/(cm·K). High local stress can even cause the damage of crystal, which limits the increase of pumping power [9][10][11][12]. In addition, the Nd:YVO4 absorption cross section for π and σ polarizations differ by a factor of 3.7 at 808 nm.…”

Abstract:We report a stable optical fiber pumped Nd:YVO4 all solid state regenerative amplifier with all fiber picosecond laser as seed source. 888 nm Yb optical fiber lasers was chosen as pump source to reduce quantum defect for improved thermal performance. At the repetition rate of 99.6 kHz, maximum power of 19.63 W with 36 ps pulse duration were achieved when seeded by a 150 mW picosecond oscillator. The wavelength delivered was 1064.07 nm with spectral width of 0.14 nm.
