.. [Clearly show whole abstract] parametric oscillator. The 2 independently targeted beams were created to overlap In the crystal. The concentrating parameters of The 2 beams have been with regard to the identical. The concentrating operate developed by Boyd and Kleinman for tightly focused beams was prolonged to periodically poled crystals as a way to suit the temperature-tuning curve. A 0.66%/W performance was obtained for the primary difference frequency mixing course of action.
Output idler energies around the microjoule stage are obtained with highest conversion effectiveness of 11% for your amplifier phase, that is more than two times better than the final results attained with an analogous sample in the greatly distribute content AgGaS 2 .
Besides the compactness and benign functioning characteristics, it had been the big adaptability in layout and output qualities that led towards the achievement of solid-condition lasers over the past forty a long time.
A straightforward system for decreasing the decline that is due to depolarization ensuing from thermally induced worry birefringence in stable-point out lasers is reported. The procedure works by using just one intracavity quarter-wave plate with its quickly or gradual axis aligned parallel to the popular plane of polarization, defined by an intracavity polarizer.
Self-referenced octave-wide subharmonic GaP optical parametric oscillator centered at three μm and pumped by an Er-fiber laser
We report the implementation of a KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Together with sign and idler, it could be continuously tuned from one.261 through two.532 μm by different the pump wavelength. Two major advancements have been attained, such as the relationship of your signal and idler tuning ranges as well as the substantial output pulse energy with the signal and idler tuning ... [Show comprehensive abstract] ranges. The first enhancement was realized by discovering two particular sets of period-matching angles. The 2nd improvement was realized by utilizing 5 sets of resonator mirrors for oscillating either sign or idler.
Two parametric four-wave-mixing (FWM) processes in Rb atoms are studied utilizing perturbation concept beneath the affliction of rotating wave approximation. The 2 parametric FWM procedures are coupled when they're psyched coherently by a brief laser pulse using a bandwidth encompassing the two corresponding higher energy stages in The 2 FWM processes.
We current a numerical review for the design of productive MgO:PPLN centered pulsed nanosecond optical parametric oscillator (OPO), with enter pump pulses of prime-hat transverse depth profile, plus a double-go pump cavity configuration. Specifically, we examine the influence of domain form on the conversion effectiveness. We regarded as two varieties of domain buildings: "ideal vertical-wall" and "wedge-formed" domains and our numerical benefits clearly show that at bigger pump pulse energies, the conversion effectiveness saturates, and also the saturated efficiency is almost impartial of your area shapes.
What's more, we done a numerical simulation of chirped-pulse OPOs (CPOPOs) and uncovered the spectral profile on the output from the CPOPO was relevant to both of those the parametric get profile from the nonlinear crystal as well as intra-cavity substantial-buy dispersion.
The click here 3rd harmonic of CO2-laser radiation has long been attained by passing the laser beam through two CdGeAs2 crystals in tandem, with the very first crystal oriented for second-harmonic generation and the 2nd for sum mixing. Utilizing this technique, We have now obtained a mean exterior conversion effectiveness of 1.
Straightforward system for lessening the depolarization decline resulting from thermally induced birefringence in strong-state lasers
We report a broadband optical parametric oscillator (OPO) pumped by a Yb-doped fiber laser method. By employing a 300 μm very long magnesium-doped periodically poled LiNbO 3 crystal because the parametric acquire medium and configuring the OPO as being a chirped-pulse oscillator, we acquired mid-infrared emission getting an instantaneous bandwidth covering 3084�?466 nm. This result represents, to the top of our awareness, the widest instantaneous bandwidth acquired from a Yb-fiber-laser-pumped singly resonant OPO, demonstrating the immense opportunity of chirped-pulse oscillation in scaling the instantaneous bandwidth of extremely-rapidly OPOs.
A pulsed TEA CO2 laser was utilized to investigate the impact of pump radiation parameters (mode construction, wavelength, and pulse duration), concentrating conditions, absorption coefficient, and temperature on the efficiency of conversion into the second harmonic and on angular dependences of section matching in ZnGeP2 crystals. Good settlement betweeen experimental and theoretical success is noticed. Examine more
