摘要： A high-power laser, especially one with a gaseous excitation medium, having an unstable optical resonator is disclosed. Fully reflecting mirrors, whose planes of curvature are parallel to one another, form the ends of the unstable optical resonator. A third mirror is concavely curved in a plane perpendicular with respect to the other two mirrors. The mirrors have a rectangular cross section and are preferably metallic. The mirrors constituting the ends of the unstable optical resonator form a confocal resonator.

摘要： The lasing action in an unstable optical resonator is controlled as to frequency by limiting frequency selectivity to an axis-near beam. The control is provided preferably outside the cavity by means of active or passive elements. A passive element returns a frequency-controlled beam into the cavity, an active element injects a control beam at the desired frequency.

摘要： An apparatus and process for pumping a lasing media (preferably krypton fluoride) over a 500 nanosecond period and thereafter compressing and focusing to a target with a final 10 nanosecond compression wave is disclosed. An exciting 10 nanosecond pulse is shaped in an overall rectangular shape with the major axes vertically aligned and this shaped beam directed upwardly and to the side of a normal extending between parallel and opposed mirrors at remote ends of a chamber. The chamber includes at the top thereof a plurality of stripper mirrors aligned along axes substantially normal to the beam path and tilted upwardly to shave successive segments off the upper portion of the beam. Beam passage opposite to the direction of stripper mirror emission produces a series of emitted shaved beam segments each spaced temporally in accordance with stripper mirror separation. The discrete beam patterns are intermediately amplified, shaped, and addressed through a "scrambling" mirror system to a laser amplifier incorporated within a telescope. Typically, the telescope is angularly addressed at the lower power and inlet portion of the telescope, amplified in the vicinity of the higher power output and focused to an essentially coplanar scrambler mirror array. The final amplified output from the coplanar scrambler mirror array emits to pulse compression optical train to an outlet wherein final focus to a target for optical compression results.

摘要： A single axis resonator for use within a laser having an annular gain region. The single axis resonator extracts optical power from the annular gain region by the use of a beam expander, reflaxicon, corner cube and output coupler, wherein the optical axis of the resonator passes through the center of the output coupler. The reflaxicon transforms a substantially elliptically-shaped beam into a crescent-shaped beam which closely resembles the shape of a section of the annular gain region. The crescent-shaped beam is reflected through the gain region several times to build up energy before being translated back into its original shape for reflection out of the laser by the output coupler.

摘要： A plurality of mirrors is arranged in spaced relationship forming a laser oscillator cavity, a diffraction coupler and a focusing system. The oscillator cavity is formed between a concave mirror and a flat centrally located compound convex mirror, the cavity being proportioned to provide oscillation of the laser electromagnetic energy in the fundamental mode and the convex mirror being formed to diffract laser energy out of the oscillator. An annular mirror positioned intermediate to said concave and convex mirrors, collects said diffracted energy and focuses it as a nearly diffraction limited laser spot at the work area.

摘要： In order to improve a solid laser, in particular a solid disk laser, comprising a resonator (40) which defines a resonator radiation field (30) and at least one solid disk (12) penetrated by the resonator radiation field (30), in such as way that the thermal lens effect can be compensated, at least essentially, it is proposed that the resonator radiation field (30) reflects off of at least one first adaptive mirror unit (50, 70) for the purposes of being able to essentially compensate a distortion of the resonator radiation field (30) due to a thermal lens effect of the at least one solid disk (12). An adaptive mirror unit (50) can be realized by a heated (58a, 58b) glass pane (54) with a HR layer (52), for example, or by a pressure-induced deformation by a fluid (78) in a volume (76) which is enclosed by the mirror (72, 74).
