High-power single-longitudinal-mode VECSEL at 1.55 μ with an hybrid metal-metamorphic bragg mirror
01 January 2007
Optically-pumped vertical-external-cavity surface-emitting laser at 1.55 μm emits 77 mW CW single-mode output power with a SMSR above 60 dB at 20°C. Linewidth measurements showed the importance of low frequency fluctuation stabilization.
