The master oscillator is carefully designed to generate
a seed pulse that is well behaved both temporally and spatially. Temporally
the MO output has a smooth near Gaussian shape with a FWHM of 800 ps
and a pulse-to-pulse time jitter of less than 10ps. Spatially, the
output is TEM00 and close to diffraction limit with an M2
of less than 1.1. The energy output from the MO is in a standard BriteLight
configuration 1 mJ/pulse and can be operated up to 1,000 Hz. The combination
of a short, and temporally smooth pulse, high repetition rate, and
excellent spatial mode is achieved by using a proprietary diode pumped
geometry of the master oscillator, which ensures a close to perfect
top hat profile of the gain profile, and by a cavity design which incorporates
a Q-switch, an acousto-optical modulator and a cavity dumper. The use
of a cavity dumper provides for an optional pre-pulse to be added as
an option. BriteLight can also be configured to support a wide range
of other pulse lengths.
