Abstract:
A novel form of extended-cavity diode laser attains robust tunable single-frequency operation with narrow linewidth. The laser cavity includes a self-pumped photorefractive phase-conjugate reflector for wavelength-adaptive narrowband feedback and a compact high-finesse tunable intracavity ring filter for single-longitudinal-mode selectivity and control. Its performance around 830 nm is verified with a simple Fabry-Perot laser diode and by Doppler-free two-photon spectroscopy in atomic cesium.
