Abstract

A singly-resonant continuous-wave optical parametric oscillator (cw-OPO) pumped by a fiber-amplified diode laser is described. Tuning of the pump source allowed the OPO output to be tuned continuously, without mode-hops, over 110 GHz in 29 ms. Discontinuous pump tuning over 20 nm in the region of 3.4 µm was also obtained. The rapid and continuous idler tuning was demonstrated by the measurement of a methane absorption spectrum. We believe this to be the first example of a singly-resonant OPO pumped by a fiber-amplified diode laser and the mode-hop free tuning range to be the highest reported for a cw-OPO.

Variation of OPO output wavelengths (lower plot), and corresponding idler output power (upper plot), during pump tuning by seed laser DBR section alone. PPLN grating period was 29.75 µm and temperature was 180.5°C. Calculated tuning data was derived using the Sellmeier equations of Jundt [10].

Upper trace: Rapid, mode-hop free tuning of the seed laser over 110 GHz observed in the transmission of a Fabry-Perot interferometer with 7.1GHz FSR. Lower trace: corresponding OPO idler tuning observed in the transmission through a 90 cm cell containing 15 mbar CH4 buffered to 0.52 bar in air (solid line), calculated cell transmission derived from HITRAN data (dashed line). Pump tuning axis was calibrated from the Fabry-Perot transmission and an absolute frequency reference, measured under static conditions, is indicated. A corresponding idler frequency reference is indicated for the measured and calculated plots. The signal frequency remained constant throughout the measurement. The total time scale represents one half of a single period of the 17 Hz tuning function.
