Abstract

We present detailed design considerations and performance of a singly resonant cw mode-locked optical parametric oscillator based on KTiOPO4. The oscillator is synchronously pumped by 2.2-ps, 1.064-μm pulses at a 75-MHz repetition rate with 4-W average power generated by temporal compression of pulses from a lamp-pumped mode-locked Nd:YAG laser. We obtained output pulses 2-3 ps long with hundreds of milliwatts of average power from 1.57 to 1.59 μm in the signal branch and from 3.21 to 3.30 μm in the idler branch. At three times above threshold we measured the pulse width of the 1.573-μm signal to be ~2.8 ps, and the corresponding spectral width was ~1.5 nm, indicating that the time–bandwidth product is 0.51. The total conversion efficiency as measured by the pump-pulse depletion is 15%. With active stabilization of the pump laser, the amplitude fluctuation of the oscillator is <15% peak to peak.

Schematic of the cw synchronously pumped KTP OPO pumped by temporally compressed pulses from a Nd:YAG laser. 2% T/AR, output coupler with 2% transmission at the signal wavelength and antireflection coatings at the pump and idler wavelengths.

Background-free autocorrelation of the compressed pulses. The pulse width is 2.2 ps FWHM, assuming a Gaussian pulse.

Power fluctuations with and without the pump-amplitude stabilization: (a) the pump power, (b) the OPO output power at 1.1 times above threshold, and (c) the OPO output power at 3 times above threshold.

Fig. 5
Fig. 5

Background-free autocorrelation of the OPO output at three times above threshold. The signal wavelength is 1.573 μm. The pulse width is 2.8 ps FWHM, assuming a Gaussian pulse shape.

Spectrum of the OPO output at three times above threshold. The center wavelength is 1.573 μm. We intentionally marked the vertical lines with 2-nm spacing during the scan.
