We report a deep-mid-IR femtosecond OPO based on CdSiP2 using direct synchronous pumping by a Ti:sapphire laser, providing continuous wavelength coverage across 6–8 μm under rapid static cavity delay tuning with high output stability.
We report phase-modulation mode-locking of a continuous-wave (cw) singly- resonant optical parametric oscillator (OPO) in the near- and mid-infrared based on MgO-doped periodically poled $\hbox{LiNbO}_{3} $ (MgO:PPLN) and pumped by an Yb-fiber laser at 1064 nm. By investigating the spectral output and pulse formation characteristics of the OPO, we observe a clear transition from an unstable spectrum...
We report a broadband mid-IR femtosecond OPO tunable across 2179–3732 nm, pumped by 20-fs pulses at 790 nm, generating idler pulses of 4.3 optical cycles (33 fs) at 2282 nm, with high stability and beam-quality.
Optical parametric oscillators (OPOs) are now established as viable sources of broadly tunable radiation for spectral regions inaccessible to lasers from the visible to mid-infrared (mid-IR). Nevertheless, the output signal-idler wavelength pairs generated by an OPO are always constrained to specific combinations by energy conservation and phase-matching. On the other hand, the provision of multiple...
We demonstrate successful use of antiresonant ring interferometer for optimum output coupling in a continuous-wave singly-resonant OPO, providing 2.28 W of signal, together with 2.95 W of idler, for 23.2 W of pump power.
We report a novel architecture for cw OPOs based on antiresonant ring interferometric cavity coupling, providing two pairs of signal/idler waves with independent tuning and arbitrarily close wavelength separation.
We report a novel generic design for cw singly-resonant-parametric-oscillators(SROs) based on two crystals, providing two signal waves with arbitrary tuning from the same cavity. Using this source we generate two distinct wavelengths with frequency difference 0.556THz.
Using the out-coupling approach, an output power of up to 16.6 W (8.3 W of signal and 8.3 W of idler) from a cw singly-resonant optical parametric oscillator (SRO) for 26.8 W of pump power at an extraction efficiency to 62% is generated . The device is based on an Yb fiber laser pump, resulting in a highly compact, practical, and portable design. The Yb fiber pump laser delivers up to 30 W of single-frequency...
Continuous-wave (cw) solid-state blue sources are of interest for optical data storage, laser displays, spectroscopy, and medical diagnostics. Frequency doubling of Ti:sapphire can in principle can provide coverage in the 400-500 nm range, but at relatively high cost and complexity. Here, we describe a novel approach to the generation of cw blue radiation based on intracavity SHG of a cw singly-resonant...
We report a dispersion compensated 1-GHz femtosecond optical parametric oscillator synchronously pumped by a 76-MHz Ti:sapphire laser using a cavity longer than the fundamental synchronous cavity length with improved output power and near-transform-limit pulses.
We demonstrate a ~1 GHz femtosecond optical parametric oscillator synchronously pumped by a 76-MHz Ti:sapphire laser using a cavity longer than the fundamental synchronous cavity length. Near-transform-limited pulses with average durations of 227 fs are generated.
Efficient generation of tunable femtosecond pulses in the visible by internal frequency doubling of an optical parametric oscillator (OPO) based on 1-mm-thick periodically-poled LiNbO3 (PPLN) is reported. Synchronously pumped by a Kerr-lens-mode-locked Ti:sapphire laser at 76 MHz at 810 nm, infrared femtosecond signal pulses across 1330-1570 nm are generated by the OPO. A 1-mm-thick crystal of BiB...
