    摘要: A laser device (100), configured for generating laser pulses, has a laser resonator (10) with a gain disk medium (11) and a Kerr medium (12). The laser resonator (10) includes a first mode shaping section (13) which is adapted for shaping a circulating electric field coupled into the gain disk medium (11), and a second mode shaping section (14), which is adapted for shaping the circulating electric field coupled into the Kerr medium (12) independently of the electric field shaping in the first mode shaping section (13). Furthermore, a method of generating laser pulses (1) using a laser resonator (10) with a gain disk medium (11) and a Kerr medium (12) is described.

    摘要: Apparatus and methods for self-cleaning of optical elements in sealed environments over a wide range of operating optical frequencies prevent long-term power degradation by introducing low-pressure backfill of a reactive gas such as oxygen into a vacuum chamber containing the optical elements. The backfill pressure is preferably between 10−4 torr and 10 torr, and generally between 0.1 torr and 2 torr at room temperature. The vacuum chamber may be continuously evacuated and backfilled, or may be sealed after evacuation and backfill is performed.

    摘要: Methods and constructions for cryogenically cooled solid state lasers are provided that allow the cooling channels to be embedded within the buffer heat sinks used to conductively cool the laser medium. Several gain medium geometries are disclosed that are compatible with efficient and straight forward cryogenic cooling techniques using practical pump chamber designs while eliminating the need for the pump light to traverse the cryogenic layers and allowing for smooth temperature cycling. A number of active material configurations that can be generally adapted for pumping by high power diodes, including slab, thin disk, active mirror, and rod geometries, are shown to be compatible with the cryogenic cooling approaches. Modeling results based on the preferred cooling configurations indicate substantial improvement in the performance of common solid state lasers, including Nd- and Yb-doped lasers. These improvements have been realized in a multiple thin-disk Yb:YAG folded resonator configuration.
