Nd:sapphire channel waveguide laser

Nd-complex-doped polymer channel waveguide laser

Polymer waveguides have emerged as a viable technology for integrated optical devices due to their high packaging density, low cost, capability of integration with other material systems, and ease of fabrication and modification of their chemical structure. This latter property offers enormous flexibility in the design of waveguide laser media. Although laser action has been achieved in many op...

Compact mid-infrared Cr:ZnSe channel waveguide laser

Compact Cr:ZnS channel waveguide laser operating at 2,333 nm.

A compact mid-infrared channel waveguide laser is demonstrated in Cr:ZnS with a view to power scaling chromium laser technology utilizing the thermo-mechanical advantages of Cr:ZnS over alternative transition metal doped II-VI semiconductor laser materials. The laser provided a maximum power of 101 mW of CW output at 2333 nm limited only by the available pump power. A maximum slope efficiency o...

Low threshold monocrystalline Nd:(Gd, Lu)2O3 channel waveguide laser.

We report the first waveguide laser based on a rare-earth-doped sesquioxide. A 2 microm thick lattice matched Nd(0.5%):(Gd, Lu)(2)O(3) film with a nearly atomically flat surface has been epitaxially grown on a Y(2)O(3) substrate, using pulsed laser deposition. The film has been structured with reactive ion etching and a rib channel waveguide laser has been realized. Laser radiation at 1075 nm a...

Q-switched operation of a femtosecond-laser-inscribed Yb:YAG channel waveguide laser using carbon nanotubes.

We demonstrate a diode-pumped femtosecond-laser-inscribed Yb:YAG channel waveguide laser, Q-switched by using single-walled carbon nanotubes (SWCNTs) near 1029 nm. We used saturable absorber mirrors (SAMs) fabricated by depositing SWCNTs on three different output couplers. Best performance of the 9.3-mm-long ultra-compact Q-switched waveguide laser is obtained with an output coupling transmissi...
