Abstract
A laser resonator includes an OPS gain-structure that is pumped with optical pulses repeatedly delivered at a pulse-repetition frequency corresponding to a resonant frequency of the laser resonator. The laser resonator additionally includes a passive mode-locking arrangement such that the resonator delivers mode-locked optical pulses. In one example the laser resonator further includes a CW optically pumped OPS gain-structure for increasing the power of the mode-locked pulses delivered from the resonator.

A laser comprising:
- a laser-resonator terminated by first and second mirrors and folded by a third mirror, the third mirror being surmounted by a first multilayer semiconductor gain-structure including at least one quantum-well layer;
- an arrangement for optically pumping the gain-structure with optical-pump pulses repeatedly delivered at a pulse-repetition frequency corresponding to a resonant frequency of the laser resonator;
- and
- wherein the resonator is arranged such that the resonator operates in mode-locked manner when the gain-structure is optically pumped with the optical-pump pulses.
