Abstract

A high-repetition-rate Ti:sapphire laser is used to synchronously pump a type-II angle-tuned CsTiOAsO4 (CTA) optical parametric oscillator. When pumped at 809 nm, the optical parametric oscillator is tunable from 1.007 to 1.180 μm in the signal branch and from 2.590 to 4.120 μm in the idler branch. Powers as high as 235 mW are obtained in the signal branch. Pulse widths as short as 56 fs are generated at 1.115 μm. CTA is shown to have a unique combination of low walk-off and low dispersion that contributes to its high gain and conversion efficiency.

Fig. 1
Fig. 1

Schematic diagram of the cavity for the synchronously pumped OPO. The Ti:sapphire pump laser passes through the dichroic fold mirror and is offset from the signal wave, which is resonated in the cavity. The idler wave emerges as a diverging wave at an angle from the signal wave.

Fig. 2
Fig. 2

Measured power of the signal wave of the OPO versus its wavelength. The external angle is changed by 0.5 deg for each data point, and the internal angle changes from 59 to 52 deg. Normal incidence of the pump is at an internal crystal angle of 57 deg, where the signal wavelength is 1.15 μm. The output power and spectral properties are similar for output couplers having 90% and 95% reflectivity, except at the short-wavelength end, where reduced gain makes the 95% reflector necessary. The calculated idler wavelength covers the range 2.579–4.117 μm.

Spectra of the signal wave taken at four angles of the CTA crystal. The curves are well fitted by Gaussian profiles, with no evidence of self-phase modulation.

Fig. 4

Interferometric autocorrelation of the CTA OPO taken at a signal wavelength centered at 1.155 μm. The measured oscillatory wave is fitted with an upper and a lower envelope calculated for a Gaussian wave having a width of 56 fs.
