Intracavity generation of 610 nm light by periodically poled near-stoichiometric lithium tantalate
2009
Intracavity frequency doubling of an optically pumped GaInNAs semiconductor disk laser by a periodically poled near-stoichiometric lithium tantalate crystal has been investigated. Stable second-harmonic generation at 610nm has been achieved with an output power of 730mW, limited only by the spectral acceptance range and Fresnel losses of the crystal. Spectral tuning of 8nm was realised with a Fabry-Perot etalon. © The Institution of Engineering and Technology.
