摘要： A method for assembling an optically pumped solid-state laser having an extended cavity is disclosed. The method comprises the steps of providing a casing (12, 13, 14, 202), mounting a TEC (16) and a base plate (17, 201) in the casing, and mounting a plurality of laser components (205-215) on the base plate using a UV and heat curing adhesive. Once the laser components are correctly positioned and aligned on the base plate, the adhesive is pre-cured using UV radiation. Final curing of the adhesive is obtained by subjecting the entire laser package to an ambient temperature of at least 100 °C. The base plate is preferably selected to have a CTE similar to that of the laser components in order to facilitate the high temperature curing. A preferred material for the base plate is AISiC.

摘要： The present invention relates to a method for the periodic domain inversion of ferroelectric flux-grown crystals that are low conductive or made low conductive. The invention also relates to an arrangement for monitoring the domain inversion of crystals while using a laser. The invention also relates to the use of crystals in applications of periodic domain inverted crystals, partly for generating light (electromagnetic radiation) at new wavelengths by non-linear optical frequency mixing (frequency doubling, difference frequency generation, summation frequency generation, optical parametric oscillation, etc.) and partly for electro-optical applications, such as light beam modulation, and partly for acoustic applications. such as the generation of acoustic waves from electric voltages applied across the crystal.

摘要： A new principle for a tunable optical parametric oscillator (OPO) and a related method are disclosed. An OPO is tuned by setting the temperature of a non-linear element to select a desired signal/idler combination, and narrow-band operation is effected by tuning a birefringent filter in the OPO to a temperature setting at which the filter matches the selected signal/idler combination, wherein broad and stable tunability is obtained by virtue of at least two different temperature settings of the non-linear element being matched to a single common temperature setting of the birefringent filter.

摘要： A laser arrangement is provided, in which a Lyot filter arrangement is operative to effect single mode operation. The birefringent element of the Lyot filter arrangement has a cavity folding mirror on one side thereof and a polarizing element on another side thereof, such that the free spectral range of the Lyot filter is improved. Preferably, the Lyot filter arrangement and the laser gain material are located in different branches of the folded cavity.

摘要： A method of generating coherent radiation, wherein a first fundamental beam of radiation from a four level laser and a second fundamental beam of radiation from a three level laser are mixed in a non-linear body, to obtain an output beam at the sum frequency of the two fundamental beams. The invention also relates to an arrangement for carrying out the method.

摘要： The invention relates to a multi-wavelength laser module (1) comprising a base plate, a plurality of radiation sources mounted on the base plate, at least one telescope (4) comprising a first lens (5) and a second lens (6) wherein the second lens (6) is arranged at a distance from the first lens along a radiation beam path, thereby creating a telescopic effect. A beam angle correction plate (7, 7', 7") is arranged between the first lens (5) and the second lens (6) in the radiation beam path, the beam angle correction plate (7, 7', 7") being angled in relation to the radiation beam path so as to parallel shift the radiation beam inside the telescope and thereby adjust the pointing direction of the radiation beam after passage of the telescope. The invention further relates to a method for assembling a multi-wavelength laser system provided with telescopes with such beam angle correction plate (7, 7', 7").
