A stable high-power waveguide resonator second harmonic device

چکیده
We report on a highly efficient waveguide resonator device for the production of 775 nm light using a titanium indiffused LiNbO3 waveguide resonator. The device stably produces up to 110 mW of second harmonic power with 140 mW incident on the device an external conversion efficiency of 75%. The cavity length is also locked, using a Pound-Drever-Hall type locking scheme, via one of two methods involving feedback to either the cavity temperature or the laser frequency. Both locking schemes result in a stable output power of at least 10 mW over one hour.

Harmonic generation in silicon nitride ring resonators.
We demonstrate second- and third-harmonic generation in a centrosymmetric CMOS-compatible material using ring resonators and integrated optical waveguides. The χ(2) response is induced by using the nanoscale structure of the waveguide to break the bulk symmetry of silicon nitride (Si3N4) with the silicon dioxide (SiO2) cladding. Using a high-Q ring resonator cavity to enhance the efficiency of ...

A nonlinear Al(x)Ga(1-x)As waveguide consisting of a quasi-phase matched heterostructure embedded in a microcavity has been designed and fabricated. The microcavity resonator is formed by Al(2)O(3)/Al(0.32)Ga(0.68)As multilayer mirrors located above and below the waveguide core. The cavity resonantly enhances the surface emitting second-harmonic generation. The SH conversion efficiency has been...

We report on the efficient generation of continuous-wave, high-brightness green laser radiation. Green lasers are particularly interesting for reliable and reproducible deep-penetration welding of copper or for pumping Ti:Sa oscillators. By intracavity second-harmonic generation in a thin-disk laser resonator designed for fundamental-mode operation, an output power of up to 403 W is demonstrate...

Second harmonic generation in Ti:PPLN waveguide resonators is investigated as a means of enhancing the conversion efficiency. Using a matched resonator of 65 mm length a record conversion efficiency of 10.3 %/mW is achieved with 0.5 mW fundamental power at λf = 1531 nm. Introduction Second harmonic generation (SHG) in waveguide resonators has been investigated in detail many years ago [1,2]; at...
