We present a micro-integrated laser module based on an amplified diode laser and second harmonic generation which is a promising candidate for a green light source in next-generation 3D holographic displays. The light emitted by the amplified laser has a wavelength of 1064 nm, reaches a power up to 8.2 W and has a long coherence length of >400 m. For second harmonic generation, we tested two geometries of periodically poled lithium niobate crystals in single pass: a bulk crystal and a planar waveguide crystal. With the planar waveguide crystal, we achieve an output power >900 mW and a coherence length >20 m at a wavelength of 532 nm. [ABSTRACT FROM AUTHOR]

Red-emitting lasers for display applications require high output powers and a high visibility. We demonstrate diode lasers and modules in the red spectral range based on AlGaInP with optical output powers up to 1 W and a nearly diffraction limited beam. These high-luminance light sources based on tapered lasers are well suited for laser TVs and projectors for virtual reality simulators based on the flying spot technology. Additionally, we developed diode lasers with internal distributed Bragg reflector (DBR) surface gratings. These DBR tapered lasers and master-oscillator power-amplifiers based on DBR ridge-waveguide lasers and tapered amplifiers feature high power, single mode emission with coherence lengths up to several meters, which are suitable for the next-generation 3D displays based on holography.

We report the first operation of a diode-side-pumped Nd:YVO4 laser in a bounce geometry at 1342 nm. Oscillator output power of 13.7 W in multimode is demonstrated with 38% slope efficiency and 10 W of single mode output with M2<1.1. A master oscillator power amplifier (MOPA) version of the bounce-geometry produces 20 W of output power. These results represent the highest power at 1342 nm from a Nd:YVO4 oscillator and oscillator-single-amplifier MOPA system. [Copyright &y& Elsevier]
