.. [Display entire summary] parametric oscillator. The 2 independently concentrated beams were being made to overlap inside the crystal. The focusing parameters of The 2 beams have been regarding the exact. The focusing function created by Boyd and Kleinman for tightly centered beams was extended to periodically poled crystals so as to healthy the temperature-tuning curve. A 0.66%/W efficiency was acquired for the primary difference frequency mixing method.
Outcomes of thermal conductivity measurements are noted for a number of of the more lately designed nonlinear optical crystals. New or substantially revised values of thermal conductivity ended up acquired in 6 resources. Noteworthy thermal conductivities calculated ended up People for AgGaS2 [0.014 W/(cm K) and 0.
In addition to the compactness and benign working functions, it absolutely was the large overall flexibility in style and output properties that led to your good results of reliable-point out lasers over the last 40 several years.
Scientific tests of practical pump laser technologies ideal for ultrafast femtosecond OPOs based on CdSiP 2 are mentioned, plus the favorable linear and nonlinear optical Houses, as well as exclusive stage-matching qualities of CdSiP two , are presented working with The latest Sellmeier equations for the material. The explained experimental success stand for the best output pulse Electricity and report normal power while in the ultrafast picosecond and femtosecond time scales throughout the six–7 μm spectral variety so far.
On this function, we current exactly what is, to our understanding, the 1st measurements from the quantum phase diffusion sound of a cw OPO. Study more
We report the implementation of the KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Which include sign and idler, it may be continually tuned from one.261 via two.532 μm by various the pump wavelength. Two important improvements were obtained, such as the relationship of the signal and idler tuning ranges and the large output pulse Electrical power through the signal and idler tuning ... [Show full summary] ranges. The primary enhancement was accomplished by getting two specific sets of phase-matching angles. The second enhancement was recognized by utilizing 5 sets of resonator mirrors for oscillating both sign or idler.
Two parametric 4-wave-mixing (FWM) procedures in Rb atoms are analyzed using perturbation idea beneath the ailment of rotating wave approximation. The 2 parametric FWM processes are coupled when they are thrilled coherently by a brief laser pulse using a bandwidth encompassing The 2 corresponding higher Strength concentrations in the two FWM procedures.
Pumping mid-IR optical parametric oscillators close to 1 μm is eye-catching for its simplicity and electric power scaling capability. To this purpose, large bandgap non-oxide nonlinear crystals are desired.
Vibrational spectra of Li-made up of nonlinear crystals as well as their software in THz radiation era are discussed. Using an example of LiGaS2, the defect effect on spectroscopic attributes is proven. Superior-temperature annealing in an appropriate atmosphere will allow 1 to eliminate extended and issue defects also to improve the transparency. Electrical power framework and parameters of main place defects including anion vacancy (F-Centre) and cation antisite defect GaLi calculated from the 1st ideas agree perfectly with the experimental benefits.
stabilize and tune the OPO, from which the sound etalon gave an improved performance. Temperature oscillations while in the PPLN crystal
... The main knowledge around the refractive index of orange HGS posted by Levine et al. [35] provided only several wavelengths inside the noticeable and in the vicinity of-IR equally as an indication of your feasibility of the crystal for birefringent stage-matching. The refractive indices to the orange stage were calculated and tabulated between 0.
We report a broadband optical parametric oscillator (OPO) pumped by a Yb-doped fiber laser system. By utilizing a 300 μm lengthy magnesium-doped periodically poled LiNbO 3 crystal because the parametric acquire medium and configuring the OPO as being a chirped-pulse oscillator, we attained mid-infrared emission acquiring an instantaneous bandwidth covering 3084�?466 nm. This outcome represents, to the best of our knowledge, the widest instantaneous bandwidth received from a Yb-fiber-laser-pumped singly resonant OPO, demonstrating the enormous prospective of chirped-pulse oscillation in scaling the instantaneous bandwidth of extremely-rapidly OPOs.
With this paper we theoretically examine probably the most effective pump temporal shape for pulsed Procedure of optical parametric oscillators (OPOs). The theoretical analysis contains solving the optimum Manage challenge using the charge equation formalism. The OPO optimal buildup habits is derived for almost any OPO check here configuration, and we display the ideal pump pulse condition is often a double rectangle. The main rectangle is optimized to the buildup process, although the 2nd a single is optimized for that continuous point out, and each rely otherwise over the OPO mirror reflectivities along with the readily available pump Electrical power and maximum peak energy.
Diode-pumped optical parametric oscillation continues to be demonstrated for The 1st time to our awareness in a single Nd:MgO:LiNbO3 nonlinear crystal. The crystal is pumped by a semiconductor diode laser array at 812 nm. The Nd³�?ions take up the 812-nm radiation to deliver 1084-nm laser oscillation.
