(Color online) Resonator layout. LD, pump diode system; PO, optics for pump focusing; LC, laser crystal; SA, saturable absorber; OC, output coupler.
Pulse trace recorded by the fast oscilloscope, corresponding to the shortest and most intense pulse generated. Inset: collimated output beam as recorded by the charge coupled device camera used for measurements.
Single longitudinal mode spectrum recorded by the optical spectrum analyzer. For comparison is shown the free spectral range of the long resonator.
Evolution of during pulse formation. The insert shows, for comparison, the same evolution for an actively -switched laser evidencing the much shorter buildup time. The legend is the same for both the figure and the insert.
