Single-Frequency CW Vertical External Cavity Surface Emitting Semiconductor Laser at 1003 nm and 501nm by Intracavity Frequency Doubling
Résumé
This work reports single-frequency laser oscillation at λ = 1003.4 nm of a diode-pumped vertical external cavity surface-emitting semiconductor laser for metrological applications. A low thermal resistance of the semiconductor active component is achieved by solid-liquid interdiffusion bonding onto a SiC substrate. The spectro-temporal dynamics of the laser is theoretically studied. Experimentally, an output power of 1.7 W is demonstrated in free running operation, and up to 500 mW in a true single longitudinal mode. Furthermore, single-frequency laser emission at λ = 501.7 nm is obtained by intracavity frequency doubling, resulting in a total output power as high as 62mW.
