Room-temperature continuous-wave operation of Ti:sapphire buried channel-waveguide lasers fabricated via proton implantation.
Fabrication and laser operation of proton-implanted Ti:sapphire buried channel waveguides is reported for the first time to our knowledge. Without any postimplantation annealing of the structures, continuous laser operation near 780 nm was demonstrated at room temperature at an absorbed pump power threshold of 230 mW. Single-transverse-mode laser emission was observed with measured beam propaga...
متن کاملDiode Pumped Planar Waveguide/Thin Slab Solid-State Lasers
Diode-pumped solid-state lasers (DPSSLs) with high power and good output beam quality are widely used in material processing, communication, remote sensing, and medical treatment. A preferable diode-pumped solid-state laser has the characteristics, such as high efficiency, long lifetime, high reliability, compact size and flexibility. Planar waveguide lasers can be formed by transition metal di...
متن کاملOptical coupling between monocrystalline colloidal crystals and a planar waveguide
We have experimentally demonstrated an optical material structure consisting of monocrystalline colloidal crystals and a planar waveguide. We have performed experimental studies of light coupling into the waveguide structure via colloidal gratings, as well as the multiplexing capability of the structure. Effective index obtained from measured parameters agrees well with theoretical calculations...
متن کاملLow-loss planar optical waveguides in strontium barium niobate crystals formed by ion-beam implantation.
Planar optical waveguides have been formed in strontium barium niobate single crystals by either proton or heliumion implantation. The profiles of the ordinary and the extraordinary refractive indices are deduced from dark-line mode spectroscopy. Optical barriers with depths to Deltan(e) = 2.6% for protons and Deltan(e) = 5.5% for helium are obtained. By proton implantation we find a very low i...
متن کاملContinuous-wave and passively Q-switched cladding-pumped planar waveguide lasers.
Greater than 12 W of average output power has been generated from a diode-pumped Yb:YAG cladding-pumped planar waveguide laser. The laser radiation developed is linearly polarized and diffraction limited in the guiding dimension. A slope efficiency of 0.5 W/W with a peak optical-optical conversion efficiency of 0.31 W/W is achieved. In a related structure, greater than 8 W of Q -switched averag...
