Pulses as short as 73-fs were generated from a Kerr-lens mode-locked Yb:YCa4O(BO3)3 laser at 1043 nm. To the best of our knowledge, this is the first demonstration of a Kerr-lens mode-locked Yb:YCa4O(BO3)3 laser.
We demonstrated a continuous-wave Yb:YGG laser up to 2.65 W under absorbed pump power of 4.23 W at 971 nm, corresponding to optical-to-optical efficiency of 62.6 % and maximum slope efficiency of 90.2 %.
Ytterbium (Yb) doped rare-earth garnet Y3Ga5O12 (YGG) single crystal was grown by the optical floating zone method for the first time, to our knowledge. Its structure and cell parameter were determined by X-ray powder diffraction. The thermal properties of Yb:YGG, including specific heat, thermal expansion coefficient, thermal diffusion coefficient, and thermal conductivity, were investigated. The...
We presented the first demonstration of a mode-locked Nd:GGG laser on quasi-three-level transition. With a semiconductor saturable absorber mirror for passively mode-locking, 24.7 ps laser pulses had been obtained at the wavelength of 937.4 nm.
Stable mode-locking laser pulse at 942 nm by diode-pumped Nd:GSAG laser has been demonstrated for the first time. We obtained 8.7 ps pulses at repetition rate of 95.6 MHz and average output power of 220 mW.
We demonstrated a mode-locked Nd:GdVO4 laser of operating at 912 nm. Using a semiconductor saturable-absorber mirror for passive mode locking, stable output power of 22.6 mW is obtained at a repetition rate of 176 MHz.
A diode-pumped Nd:LuVO4 continuous-wave laser operating at 916 nm was demonstrated for the first time. Output power of 11.4 mW was obtained with 11 W incident pump power, it corresponds to a slope efficiency of 0.22%.
