摘要： A continuously-pumped, repetitively-pulsed, Q-switched laser resonator includes two different gain-media which lase at about the same wavelength. By separately and variably pumping the different gain-media, the laser resonator can efficiently generate output radiation having parameters which stay constant over a much wider range of pulse-repetition frequency than would be possible were either one of the gain-media solely deployed in the resonator. In one embodiment, the laser resonator includes an arrangement for providing near real-time compensation for variations in thermal-lensing in the gain-media resulting from variations in pump-power or pulse-repetition frequency.

摘要： A laser system involving coupled distributed resonators disposed serially, with the lasing gain medium located in the main resonator and the output of that resonator being directed into a free space resonator, such that the main resonator output mirror is effectively the free space resonator. The distributed resonators end mirrors are retroreflectors. Interference occurs between light traveling towards the remote mirror of the free space resonator and light reflected therefrom, generating regions of high reflectivity. The coupling of the free space resonator to the regions of high reflectivity of the free space resonator enables the first resonator to lase efficiently, even though the true reflectivity of the main resonator output mirror outside of those regions is insufficient to enable efficient lasing, if at all. This coupled resonator structure enables lasing to occur with a high field of view and the high gain engendered by the high reflectivity regions.

摘要： A short-pulse mode-locked laser is configured with at least two reflective elements defining a resonant cavity therebetween, a laser gain element ("GE") placed inside the resonant cavity at normal incidence and selected from transition metal doped II- VI materials; and an optical pump emitting pulsed output to synchronously or quasi- synchronously pump the GE at a pulse repetition rate frequency f pUmp , the pump being configured so that the f pump substantially matches an inversed round trip time in the resonant cavity f laSer - f pump ~f laSer = c / 2L , where c is the speed of light, L is the length of the resonant cavity. The synchronous or quasi-synchronous pumping triggers and sustains a short-pulse emission of the laser with picosecond or femtosecond pulse durations.

摘要： A gas includes a housing having a symmetrical arrangement of upper and lower cooling members for removing heat generated in a gas- discharge excited by an electrode assembly. The electrode assembly is clamped between the cooling members and is itself essentially symmetrically arranged. The cooling members and the electrode assembly are mechanically isolated in the housing by a surrounding diaphragm-like arrangement that connects the cooling members to side-walls of the housing. An RF power-supply for supplying the electrode assembly is mounted on one of the sidewalls to avoid disturbing the symmetry of the cooling and electrode arrangements.
