摘要:
Disclosed herein is a laser module in which an optical block generating or controlling laser beams has a contact side surface made to have squareness, and neighboring optical blocks are coupled to each other in such a way that contact side surfaces thereof come into contact with each other, thus allowing the optical blocks to be aligned with each other and thereby obviating the necessity of additional alignment.

A laser resonator is provided that includes a cavity bounded by an end mirror and output coupler, and one or more gain media between the end mirror and output coupler. The laser resonator also includes a modal corrector mirror between the end mirror and output coupler. The modal corrector mirror includes a controllable-profile faceplate including an optically-treated front surface, and an array of static actuators. Each static actuator includes an adjustable element, and a compliant mechanism located between the adjustable element and faceplate. The adjustable element is configured to exert a selectable, localized push-pull force on the faceplate via the compliant mechanism, and the compliant mechanism is configured to scale the respective force.

A solid-state lasing device includes a micro-chip oscillator (MCO) affixed to a first tube, and a volume Bragg grating (VBG) plate affixed to a second tube. The second tube is configured to be telescopically coupled to the first tube with a slip fit such that the VBG plate is concentrically aligned with and is positioned at a specified distance from the MCO.

The slant of a first mirror (21), the slant of a second mirror (22), and the laser output when the slant of the first mirror (21) is an initial value and when the slant of the first mirror (21) is made to move from the initial value by exactly a predetermined value in the positive and negative directions are used as the basis to calculate a first approximation curve of the laser output with respect to the slant of the first mirror (21) and second approximation curve of the laser output with respect to the slant of the second mirror (22), set a value which corresponds to a local maximum value of the first approximation curve as the slant of the first mirror (21), and set a value which corresponds to a local maximum value of the second approximation curve as the slant of the second mirror (21).

A wavelength-tunable laser system includes an optical fiber collimator array having at least two ports, an optical amplifier connected to one port of an optical fiber, an optical coupler for coupling light incident from the optical amplifier and transmitting the coupled light to another port, a diffraction grating plate for guiding each wavelength component of light incident from the optical fiber collimator array in a different direction, and an Opto-Very Large Scale Integration (Opto-VLSI) processor.
摘要:
A laser cavity is provided by a reflecting spherical substrate with an array of emitters having a mode size. Each emitter has an axis aligned with a radius of the spherical substrate. A single mode waveguide is aligned with the array at an optical coupling distance less than the radius of the spherical substrate. A reflector substantially coincident with an end of the waveguide combines with the reflecting spherical substrate as a cavity.

A method for producing extreme ultraviolet light includes producing a target material at a target location; supplying pump energy to a gain medium of at least one optical amplifier that has an amplification band to produce an amplified light beam; propagating the amplified light beam through the gain medium using one or more optical components of a set of optical components; delivering the amplified light beam to the target location using one or more optical components of the optical component set; producing with a guide laser a guide laser beam that has a wavelength outside of the amplification band of the gain medium and inside the wavelength range of the optical components; and directing the guide laser beam through the optical component set to thereby align one or more optical components of the optical component set.

Certain example embodiments of this invention relate to waveguide lasers (e.g., RF-excited waveguide lasers). Certain example embodiments of this invention provide an optical mounting scheme for use with a waveguide laser. In certain example embodiments, a carrier including an optic holder may be provided. An optic may be mounted to the carrier via a face-sealing epoxy. An optic interface may be formed at least in part by the epoxy. The optic interface may be a thin layer of a substantially uniform thickness located between the carrier and optic face. The carrier and/or the optic holder of the carrier may be beveled proximate to where the optic interface is formed and, optionally, proximate to where the epoxy is applied. In certain example embodiments, the epoxy may be applied to only the optic's face and/or to the optic holder's face. In certain example embodiments, the waveguide laser may further comprise a vacuum vessel, and the carrier may be attached to the laser such that the optic and/or the optic interface attached to the carrier fit inside of the vessel.

摘要:
A support unit (20a) for supporting an OPM holder (15a) so as to be vertical to the laser beam axis is disposed in the lower part of the OPM holder (15a). A rotary shaft (19) is inserted into the support unit (20a) and rotary shaft support unit (20b), and the OPM holder (15a) and DT base (17) are assembled together. Thus, a rotation support unit (200) is composed. The rotation support unit has a degree of freedom in the rotating direction of arrow (202). On the other hand, in the lower part of an RM holder (15b), a support bar (21) is provided. At the DT base (17), a rotating element (22) and a rotating element support unit (23) supporting the rotating element are composed so as to support the support bar. Thus, a slider structure (220) slidable in the optical axis direction is formed. The slider structure has a degree of freedom in the direction of arrow (222).
