63.5L: Late-News Paper: Planar-Waveguide Green Laser for Laser TV

We have newly developed an ultra‐compact, highly efficient and high‐power green laser for a light source of laser TV. A planar‐waveguide configuration improves performance of solid‐state green laser dramatically. The laser consists of essential minimum three devices (a pump LD, a planar‐waveguide Nd:YVO4 and a planar‐waveguide PPMgLN). Output green peak power of 11.4‐W with the corresponding electrical efficiency of 21% is demonstrated. In addition, temperature insensitive features are also proved. The size of developed laser module is as small as 5cc. We believe this laser is the most suitable green laser light source for laser TV at present.
