  We report the first direct femtosecond laser-writing of buried channel
waveguides in monocrystalline ZnS. We also report the first single-mode Cr:ZnS
depressed cladding buried waveguide laser manufactured by femtosecond laser
writing. The laser yields 150 mW average power at 2272 nm wavelength with 11%
slope efficiency. A depressed cladding waveguide with propagation loss of 0.62
dB/cm at 1030 nm allowed to obtain spectral broadening under
femtosecond-pumping at 1030 nm.
