Abstract: Single crystals are described that contain several regimes within the crystal that perform different functions related to the enhanced performance of a laser gain medium. At least one regime of the single crystals can be utilized to suppress amplified spontaneous emission and parasitic oscillation in a laser gain medium. A single crystal can include core and cladding regions, the cladding region providing amplified spontaneous emission suppression. The core region of the crystal can include as dopant one or more ions that take part in the lasing when suitably pumped. The amplified spontaneous emission suppression region can include as dopant one or more ions that can prevent additional spontaneous emission that can to depletion of the upper laser states, thus reducing laser performance including one or more ions that absorb spontaneously emitted photons and/or a higher concentration of the active lasing ions of the core.

Abstract: A slab laser and its method of use for high power applications including the manufacture of semiconductors and deposition of diamond and/or diamond-like-carbon layers, among other materials. A lamp driven slab design with a face-to-face beam propagation scheme and an end reflection that redirects the amplified radiation back out the same input surface is utilized. A side-to-side amplifier configuration permitting very high average and peak powers having scalability is also disclosed. Cavity filters adjacent to pump lamps convert the normally unusable UV portion of the pump lamp spectrum into light in the absorption band of the slab laser, thereby increasing the overall pump efficiency. The angle of the end reflecting surface is changed to cause the exit beam to be at a different angle than the inlet beam, thereby eliminating the costly need to separate the beams external to the laser with the subsequent loss of power.

Abstract: 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.

Abstract: Described herein are devices and techniques for suppressing parasitic modes in planar waveguide amplifier structures. One or more of the side and end facets of a planar waveguide amplifier are angled with respect to a fast axis defined in a transverse plane perpendicular to a core region. A relationship between glancing in-plane angles of incidence and threshold bevel angles θT can be used to select side bevel angles θS to suppress parasitics by redirecting amplified spontaneous emission (ASE) from the core. It is possible to select the one or more bevel angles θS to be great enough to substantially redirect all but ballistic photons of any guided modes, effectively narrowing a numerical aperture of the planar waveguide amplifier along a slow axis, defined in a transverse plane perpendicular to the fast axis. Beneficially, such improvements can be realized for three part waveguide structures (e.g., cladding-core-cladding), with substantially smooth edge facets.
