    摘要： A cascaded harmonic generator, for cascaded optical harmonic generation from an optical beam provided by a laser source, may include a second harmonic generator to generate a second harmonic optical beam based on a residual beam associated with the optical beam. The cascaded harmonic generator may include a third harmonic generator to generate a third harmonic optical beam based on the second harmonic optical beam and the optical beam. The third harmonic generator may be positioned in an optical path upstream from the second harmonic generator. A harmonic generator delay time, associated with the optical path, may be approximately equal to, or may be an approximate integer multiple of, a laser source round-trip time.

    摘要： A pulsed solid-state thin-disk laser comprises an optical resonator and a solid-state laser gain medium placed inside the optical resonator. The laser gain medium is in the shape of a thin plate or layer with two end faces, the extension of the end faces being greater than a thickness of said plate or layer measured in a direction perpendicular to one of the end faces. One of the end faces comprises a cooling surface, via which the laser gain medium is cooled. A pumping source is provided for exciting the laser gain medium to emit electromagnetic radiation. The thin-disk laser further comprises means for passive mode locking placed inside the optical resonator. The mode-locking means are preferably a semiconductor saturable absorber mirror (SESAM). The laser offers a high average power, a good beam quality, short pulses and a high efficiency. Problems such as thermal lensing, Q-switching instabilities and damages of the mode-locking means are avoided. Moreover, the output power of the laser is scalable, i.e., may be increased without increasing the above-mentioned problems.

    摘要： Intra-cavity and/or inter-cavity sub-resonators (10, 20, 22, 50, 52, 32, 54) with dielectric coated mirrors (10, 50, 52, 54) have anti-reflection and high-reflection coatings to attain high efficiency third (32) and higher order harmonics generation of laser radiation. Main-resonators and sub-resonators enhance the fundamental and harmonic oscillation, respectively, which result is high conversion efficiency of third harmonics (32) and higer, such improved lasing efficiency may be implemented in higher power lasers for improved power performance to attain over 8 W of UV output power with a high repetition rate. The use of intra-cavity THG techniques provide high efficiency by using existing high intensities of the input fundamental frequencies available in the intra-cavity region of the laser to avoid damage to components of the laser, such as the laser crystal. The THG utilizes a double-pass and/or multi-pass arrangement, which results in about a 60 % increase in output power compared to a single pass configuration. Also, blocking of UV energy generated in a return pass is performed to eliminate damage by the UV to components in the main cavity.
