.. [Exhibit whole abstract] parametric oscillator. The 2 independently focused beams were being created to overlap Within the crystal. The concentrating parameters of the two beams ended up regarding the very same. The concentrating purpose formulated by Boyd and Kleinman for tightly centered beams was prolonged to periodically poled crystals so as to suit the temperature-tuning curve. A 0.66%/W efficiency was obtained for the real difference frequency mixing process.
It's very long been predicted the stage difference between the sign and idler subharmonic outputs of the optical parametric oscillator (OPO) undergoes a random walk procedure, similar to the section diffusion of the laser [1].
Apart from the compactness and benign functioning capabilities, it was the large versatility in style and output features that led into the success of solid-state lasers during the last 40 a long time.
A simple system for cutting down the loss that is because of depolarization resulting from thermally induced strain birefringence in good-state lasers is described. The technique uses one intracavity quarter-wave plate with its quickly or gradual axis aligned parallel to the preferred plane of polarization, outlined by an intracavity polarizer.
We report new experimental results around the phase-matching Homes of yellow shade HgGa2S4 crystals for harmonic era of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers while in the 0.944-10.5910 μm variety. Additionally, we existing new Sellmeier equations that give a fantastic copy on the present experimental outcomes and also the revealed knowledge factors for second-harmonic era of CO2 laser radiation at 9.
We report the implementation of the KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Which includes sign and idler, it may be repeatedly tuned from 1.261 by way of two.532 μm by various the pump wavelength. Two key enhancements ended up attained, including the connection from the signal and idler tuning ranges as well as high output pulse Vitality with the sign and idler tuning ... [Clearly show whole abstract] ranges. The very first advancement was realized by getting two certain sets of section-matching angles. The next improvement was recognized through the use of five sets of resonator mirrors for oscillating possibly sign or idler.

stabilize and tune the OPO, from which the strong etalon gave a better general performance. Temperature oscillations from the PPLN crystal
Normalization in the absorption alerts in the PAD is performed based on the absorption signals in the fuel-loaded
The noticed file -to- two file frequency beats, originating directly from the OPO, can be utilized for self-referencing and period locking of your pump laser comb without having for supercontinuum technology. With a mean output ability of �?thirty mW , this set up may very well be valuable for a range of spectroscopic apps in the mid-IR.
In this paper we theoretically investigate probably the most productive pump temporal form for pulsed operation of optical parametric oscillators (OPOs). The theoretical Assessment consists of resolving the optimal control problem utilizing the level equation formalism. The OPO exceptional buildup habits is derived for almost any OPO configuration, and we demonstrate that the optimal pump pulse condition can be a double rectangle. The primary rectangle is optimized to the buildup method, although the second just one is optimized to the regular point out, and equally depend in another way within the click here OPO mirror reflectivities along with the out there pump Strength and maximum peak electricity.
three% rms around twelve h in great beam good quality. The in close proximity to-IR sign pulses within the OPO have a Gaussian pulse duration of �?19 ps , calculated at 1284 nm. We have investigated the temperature tuning traits in the OPO and in comparison the information with the theoretical calculations making use of the most recent Sellmeier equations and thermo-optic coefficients for your crystal. To the most effective of our information, This is actually the initial picosecond OPO according to CSP functioning at MHz repetition costs.
