1. A laser system,
comprising:
a laser cavity;
a gain medium positioned within the laser cavity;
a pump source optically coupled to the gain medium;
an input mirror positioned at a first end of the laser cavity;
an output coupler positioned at a second end of the laser cavity; a first etalon having a thickness of between 10 to 50 μm positioned within the laser cavity and configured to tune the spectral range of the laser to at least 20 nm;
and a q-switching element positioned within the laser cavity;
wherein:
the laser system is configured to provide a pulsed laser beam at a selected wavelength ranging of 1700 to 3000 nm with a tunable spectral range of at least 20 nm;
the q-switching element provides a pulse switching of a laser beam;
and wherein the gain medium, the pump source, the input mirror, the output coupler, the first etalon, and the q-switching element are at a light-pass of the pulsed laser beam.
