Single-transverse-mode Ti:sapphire rib waveguide laser.
Laser operation of Ti:sapphire rib waveguides fabricated using photolithography and ion beam etching in pulsed laser deposited layers is reported. Polarized laser emission was observed at 792.5 nm with an absorbed pump power threshold of 265 mW, which is more than a factor of 2 lower in comparison to their planar counterparts. Measured beam propagation factors M2x and M2y of 1.3 and 1.2, respec...
متن کاملSingle transverse-mode laser operation of Ti:sapphire rib waveguides
Ti:sapphire is an attractive laser medium for the development of miniature lasers with widely tunable output (650-1100 nm). However, due to its low peak emission cross section and short fluorescence lifetime, high pump power densities are required to achieve efficient CW lasing. A route to address this problem is to adopt channel waveguide geometries, which are characterized by lower laser thre...
متن کاملAn all-silicon, single-mode Bragg cladding rib waveguide.
In this paper, we demonstrate a direct method of fabricating an all-silicon, single-mode Bragg cladding rib waveguide using proton beam irradiation and subsequent electrochemical etching. The Bragg waveguide consists of porous silicon layers with a low index core of 1.4 that is bounded by eight bilayers of alternating high and low refractive index of 1.4 and 2.4. Here, the ion irradiation acts ...
متن کاملPerformance of Ar-Milled Ti:Sapphire Rib Waveguides as Single Transverse-Mode Broadband Fluorescence Sources
Rib waveguides have been fabricated in pulsed-laser-deposited Ti:sapphire layers using photolithographic patterning and subsequent Ar-beam milling. Fluorescence output powers up to 300 W have been observed from the ribs following excitation by a 3-W multiline argon laser. Mode intensity profiles show high optical confinement and the measured beam propagation factors 2 and 2 of 1.12 and 1.16, re...
متن کاملHarmonically mode-locked Ti:Er:LiNbO(3) waveguide laser.
Active mode locking of an Er-diffusion-doped Ti:LiNbO(3) waveguide laser by intracavity phase modulation to as high as the fourth harmonic (5.12 GHz) of the axial-mode frequency spacing is reported. The diode-pumped, pigtailed, and fully packaged laser with a monolithically integrated intracavity phase modulator has a threshold of 9 mW (incident pump power E(p) || c) and emits transform-limited...
