We studied Q-switching at the 3 μm, assisted by CW lasing at the 1.7 μm and the gain-switched cascade lasing at the 1.6 μm. The former increases pulse energy, the latter allows increasing pulse frequency.

We present a high-power70W, sub-50fs, 400µJ source at 200 kHz. This source is based on the high-efficiency nonlinear compression of an industrial grade 100 W, 450 fs amplifier through a gas-filled multipass cell (MPC) scheme.

We demonstrate a highly efficient, continuously tunable, diamond Raman laser operating in the blue region of the spectrum. The linewidth and tunability characteristics of a frequency-doubled Ti:Sapphire laser were transferred directly to the Stokes output, offering great potential for spectroscopic applications using an all-solid-state platform.
