Abstract: A controllable Pockels cell system has a switching unit that can apply voltage to the Pockels cell. The Pockels cell system also features a delay unit that enables setting of a precise time when voltage is applied or removed from the Pockels cell. This allows displacing in time the voltage pulse applied to the Pockels cell, in this manner also displacing in time the transmission pulse of the Pockels cell with an analyzer located behind the Pockels cell. Thus it is possible to individually control the amplitude of selected laser pulses. The switching unit can either be a simple push-pull circuit or a bridge circuit made from two push-pull circuits.

Abstract: This invention relates generally to laser systems that produce UV light and their methods of use. The phase matching of the conversion process has a broad temperature bandwidth so that precise temperature stabilization is not necessary to obtain a stable efficiency and a non-deformed laser beam with fast power modulation at high energies.

Abstract: An optical system has a diode pump source, and a gain media made of a material with an anisotropic absorption. The gain media is cut at an angle to produce substantially polarization-independent absorption of a pump beam. An optical coupler is positioned between the diode pump source and the gain media. The optical coupler produces a pump beam that has substantially equal amounts of pump power along any two orthogonal axis that are orthogonal to the pump beam in the gain medium. The wavelength range allowed for the pump source is extended.

Abstract: An optical system includes a diode pump source and a thin disk gain media. The thin disk gain media has first and second surfaces and is made of a material with an anisotropic thermal expansion. At least one of the first and second surfaces is a cooling surface. The thin disk gain media is cut at an angle to provide substantially the same thermal expansion coefficient in all directions lying in a plane that is parallel to the cooling surface. An optical coupler is positioned between the diode pump source and the thin disk gain media to direct an output from the diode pump source to the thin disk gain media.
