Single-frequency continuous-wave optical parametric oscillator system with an ultrawide tuning range of 550 to 2830 nm

چکیده
We present a cw single-frequency laser source with what is to our knowledge the largest emission range ever demonstrated, from the green to the mid-IR range. It employs a cw optical parametric oscillator with subsequent resonant frequency doubling. Typical output powers are 30–500 mW, with 160 mW at 580 nm. Modehop-free oscillation, high absolute frequency stability, 20-kHz-signal linewidth, and up to 38-GHz continuous tuning are demonstrated. Both PPLN and PPKTP are used as nonlinear materials, and their performance is compared. © 2002 Optical Society of America OCIS codes: 190.4970, 190.4360, 190.4410, 140.3600.

Continuous-wave singly-resonant optical parametric oscillator with resonant wave coupling.
We report major enhancements in the overall performance of continuous-wave singly-resonant optical parametric oscillators (cw SROs) through finite output coupling of the resonant wave. Using a cw SRO based on MgO:sPPLT pumped at 532 nm, we demonstrate improvements of 1.08 W in total output power, 10% in total extraction efficiency, and a 130-nm extension in the useful tuning range, while mainta...

A watt-level, single-frequency, continuous-wave (cw) singly resonant optical parametric oscillator (OPO) based on MgO:sPPLT is described. Pumped in the green by a frequency-doubled cw diode-pumped Nd:YVO(4) laser at 532 nm, the OPO can provide up to 1.59 W of single-frequency idler output with a linewidth of ~7 MHz at pump depletions of as much as 67%.

We report on a continuous-wave singly resonant optical parametric oscillator (SRO) based on periodically poled KTiOPO4. This is pumped by a frequency-doubled single-frequency Nd:YAG master oscillator power ampli®er system. Pump wave enhancement allowed for external oscillation thresholds around 200 mW. Up to 72 mW of idler and 28 mW of signal radiation were generated at 1.2 W pump power. Output...

A temperature-tuned continuous-wave doubly resonant optical parametric oscillator (OPO) consisting of a semimonolithic KTP crystal and a concave mirror has been designed and built. Under single-axial-mode-pair operation, we obtained a combined output power of the signal and idler light fields up to 365 mW at a pump power of 680 mW. The output wavelength of the OPO can be temperature tuned by as...
متن کاملTunable, continuous-wave, ultraviolet source based on intracavity sum-frequency-generation in an optical parametric oscillator using BiB₃O₆.
We report a continuous-wave (cw) source of tunable radiation across 333-345 nm in the ultraviolet (UV) using bismuth triborate, BiB₃O₆ (BIBO) as the nonlinear gain material. The source is based on internal sum-frequency-generation (SFG) in a cw singly-resonant optical parametric oscillator (OPO) pumped at 532 nm. The compact tunable source employs a 30-mm-long MgO:sPPLT crystal as the OPO gain ...
