    摘要： The laser resonator includes a first resonator wall, a second resonator wall that is substantially parallel to the first resonator wall and is separated from the first resonator wall in a first transverse direction thereby defining a gap having a gap width between the first and second resonator walls, and at least two laser cavity mirrors. The laser cavity mirrors are arranged to allow an intra-cavity laser beam to reflect from the output coupling mirror thereby forming a first beam spot on the output coupling mirror. The first curved mirror has a radius of curvature such that the reflection of the intra-cavity laser beam from the first curved mirror causes the first beam spot on the output coupling mirror to have a substantially symmetric shape.

    摘要： A single-cavity dual-electrode discharge cavity and an excimer laser including such a discharge cavity are disclosed. The discharge cavity may comprise a cavity body and two sets of main discharge electrodes. The cavity body may comprise a left chamber and a right chamber arranged to form a symmetric dual-chamber cavity. The left and right chambers can interface and communicate with each other at a plane of symmetry of the entire discharge cavity. The two sets of main discharge electrodes can be disposed in the left and right chambers on the upper side, respectively. According to the present disclosure, the single-cavity configuration can be used to achieve functions of dual-cavity configurations, such as MOPA, MOPO, and MOPRA. Thus, it is possible to reduce system complexities and also ensure synchronization of discharging in the discharge cavity.

    摘要： An RF excited gas discharge laser is disclosed including a housing holding the lasing gas. An electrode assembly is mounted within the housing. The electrode assembly includes a pair of elongated planar electrodes mounted in face to face relationship with a narrow gap therebetween. A pair of planar dielectric plates are positioned along the side edges of the gap to seal the discharge region. The plates extend part of the way into the gap from both sides edges of the electrodes. The inner surfaces of the electrodes are provided with an opposed trench in the region surrounding the inner edges of the plates. In this way, the exposure of the inner edges of the plates to the discharge is minimized improving performance.

    摘要： Continuously tunable and precisely wavelength-switchable fiber lasers combine fiber Bragg gratings and the transmissive filtering properties of high finesse fiber Fabry-Perot filters. This laser arrangement adapts to multiple wavelength ranges based on the selections of fiber Bragg grating and gain medium and their arrangement to create a wavelength-modulatable and simultaneously rapidly wavelength-switchable narrow linewidth all-fiber laser design. This laser arrangement further results in narrow-linewidth outputs with fast switching speeds between the selected wavelengths.
