Extended Wavelength Coverage of a Ce(3+):LiCAF Laser Between 223 and 243 nm by Sum Frequency Mixing in nu-Barium Borate.

We obtained coherent radiation in the spectral region between 223 and 243 nm by frequency mixing the tunable output of a solid-state Ce(3+):LiCAF laser with 1.064-mum radiation from a Nd(3+):YAG pump laser in a beta-barium borate nonlinear crystal.

Continuous-wave broadly tunable Cr2+:ZnSe laser.

We report room-temperature operation of an all-solid-state broadly tunable continuous-wave Cr(2+):ZnSe laser. Output power of 250 mW, an absorbed power slope efficiency of 63%, and continuous tunability from 2138 to 2760 nm are demonstrated.

Mode-locked Cr(2+):ZnSe laser.

We describe active mode locking of a Cr(2+):ZnSe laser operating near 2.5 mum. The laser produces 4.

Femtosecond pulse generation by using an additive-pulse mode-locked chromium-doped forsterite laser operated at 77 K.

Using an acousto-optically mode-locked chromium-doped forsterite laser, operated at 77 K and coupled to a nonlinear resonator containing a single-mode fiber, we have produced femtosecond pulses of 150-fs duration at 1.23 microm with useful output powers of approximately 60 mW This represents what is to our knowledge the first demonstration of femtosecond pulse generation from this laser system using the coupled-cavity mode-locking scheme.

Tunable, cw operation of a multiwatt forsterite laser.

We have obtained over 1.8 W of power from a cw chromium-doped forsterite laser operated at 77 K when it is pumped by a 7.3-W Nd:YAG laser at 1.
