    Notes: A high-power continuous-wave optical parametric oscillator based on the nonlinear material KTiOAsO4 and pumped internal to a tunable Ti:sapphire laser is described. The use of the intracavity pumping approach has enabled operation of a singly resonant oscillator (SRO), resulting in the generation of as much as 1.46 W of infrared power in a 11.5-mm-long crystal. Amplitude-stable signal and idler outputs, each in excess of 500 mW, over the respective wavelength ranges of 1.11–1.20 and 2.44–2.86 μm have been extracted from the SRO. We demonstrate up to 90% down-conversion of the optimum Ti:sapphire output power to the SRO, confirming our recent theoretical predictions. The performance characteristics of the device demonstrate that practical, stable, and efficient operation of continuous-wave SROs at watt-level output power can be readily achieved in conventional birefringent materials by exploiting the intracavity pumping approach. © 1998 American Institute of Physics.

    Notes: We have demonstrated a continuous-wave optical parametric oscillator that uses lithium triborate as the nonlinear material and a tunable Ti:sapphire laser as the pump source. By exploiting type I noncritical phase matching and a combination of temperature and pump frequency tuning, we have generated widely tunable radiation from 1.49 to 1.70 μm, limited by the bandwidth of the optical coatings. Total output powers of 30 mW and pump depletions of 40% have been obtained at two times the oscillation threshold of 360 mW. We discuss the application of this nonlinear frequency conversion process to several recently proposed experiments.

    Notes: Efficient picosecond optical parametric oscillation in LiB3O5 is demonstrated using ∼55 ps pump pulses at 523.5 nm, obtained from a frequency-doubled, mode-locked, Q-switched, diode-laser-pumped Nd:YLF laser. By exploiting temperature tuning under noncritical type I phase matching, continuously tunable radiation over the range 0.909–1.235 μm has been generated at external power conversion efficiencies approaching 50%. The oscillator has a pump power threshold of 4.5 mW, corresponding to a Q-switched pulse energy of 9 μJ, and can provide a total average output power of 8 mW at 500 Hz, in pulses of ∼33 ps duration. At five times above threshold, the internal pump depletion of the oscillator was 54%.

    Notes: We report a low-pump-threshold, all-solid-state subpicosecond optical parametric oscillator (OPO) for the mid-infrared based on periodically poled LiNbO3 and synchronously pumped by a mode-locked Ti:sapphire laser. Using a semimonolithic cavity design and hemispherical focusing, pump power thresholds of 17 mW and mid-infrared idler powers of 64 mW have been obtained in the 3.9–6 μm spectral range in a simple, practical, and compact configuration at pulse repetition rates of up to 322 MHz. The OPO delivers a signal output power of up to 280 mW at ∼35% extraction efficiency and can provide transform-limited signal pulses with durations of 0.4 ps over the spectral range of 1.00–1.14 μm. © 2000 American Institute of Physics.

    Notes: A continuous-wave pump-enhanced singly resonant optical parametric oscillator (OPO) directly pumped by a grating-stabilized external-cavity diode laser operating at (approximate)810 nm is described. The OPO was based on periodically poled LiNbO3 and could be tuned over 1.06–1.19 μm at the signal and 2.58–3.44 μm at the idler. The OPO threshold was typically 25–30 mW over the observed tuning range. Up to 4 mW of one-directional idler output was obtained for 62 mW of external-cavity diode laser pump power. The high stability of the external-cavity diode-laser pump source allowed locked, single-mode OPO operation for periods of greater than 1 h. © 2001 American Institute of Physics.

    Mode-hop-free tuning over 80 GHz of an extended cavity diode laser without antireflection coating (2001)
    [S.l.] : American Institute of Physics (AIP)

    Notes: We report 80 GHz of mode-hop-free tuning from an extended cavity diode laser (ECDL) without the need for antireflection coating on the diode facet. A large continuous tuning range was achieved by using a simple electronic circuit which simultaneously varies the diode laser current and external cavity length in an appropriate ratio. The ECDL employs a commercial, single mode AlGaAs diode laser, operating at 814 nm, in a Littrow external cavity configuration. The applicability of this technique to the most commonly available single-mode diode lasers without the requirement of antireflection coating, makes it an attractive approach for the attainment of mode-hop-free tuning over extended ranges. © 2001 American Institute of Physics.

    Notes: Abstract The operation and characterization of a high-repetition-rate singly-resonant picosecond optical parametric oscillator based on the non-linear material KTiOAsO4 and synchronously pumped by a Kerr-lens-mode-locked Ti:sapphire laser at 81 MHz is described. By utilizing non-critical type II phase-matching in a 10 mm crystal, average near-infrared output powers of 403 mW have been generated at 31% extraction efficiency. The oscillator exhibits a pump power threshold of 230 mW and with the available mirror set can provide signal tuning over 1.116–1.281 μm and idler tuning over 2.260–3.160 μm by tuning the pump wavelength over 770–896 nm. Without dispersion compensation, near-transform-limited signal pulses with durations of 1.01–1.03 ps and idler pulses with 1.61–2.91 ps duration have been obtained for 1.2 ps input pump pulses.

    Notes: Abstract We report a new source of high-repetition rate and widely tunable picosecond pulses for the near infrared. A singly resonant, cw, picosecond optical parametric oscillator based on temperature-tuned LiB3O5 and synchronously pumped by 1.8 ps pulses from a self-mode-locked Ti:Sapphire laser is demonstrated. The oscillator can provide average output powers of up to 90 mW under non-critical type-I phase matching at a pulse repetition rate of 81 MHz. Without dispersion compensation, transform-limited signal pulses with 720 fs durations have been generated at 1.2 times threshold. With the available mirror set, signal tuning over 1.374–1.530 µm and idler tuning over 1.676–1.828 µm is demonstrated for a range of pump wavelengths and phase-matching temperatures. With additional mirrors, continuous tuning throughout 1–2.7 µm should be readily attainable with a single LiB3O5 crystal.
