053 μm. The absorption spectrum of ammonia was presented to demonstrate the feasibility of your created optical parametric oscillator program for spectroscopic measurements and fuel detection.
Output idler energies within the microjoule level are acquired with optimum conversion effectiveness of 11% for the amplifier phase, which happens to be much more than two occasions a lot better than the outcomes obtained by having an analogous sample in the extensively unfold material AgGaS two .
crystals with ultrafast Yb-ion laser pump is proposed. The outcome variety a useful reference for the selection of materials
The significant conversion performance and big selection of radiation wavelength tuning will allow to hope that this materials could compete with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals in spite of the considerable difficulty of massive size crystals growth process.
During this do the job, we present what exactly is, to our know-how, the 1st measurements on the quantum period diffusion noise of the cw OPO. Read through more
This double rectangle is quantitatively described and it is in step with prior final results reported from the literature. Also, numerical simulations are accustomed to validate our analytical model over a doubly resonant OPO and present constant success. The numerical simulations also demonstrate that an optimum leading-hat temporal profile could deliver performances quite close to those achieved While using the ideal double rectangle.
Ultrafast femtosecond method-locked fiber laser performs an indispensable function in professional medical imaging, Area ranging, ophthalmology, terahertz spectroscopy, substance micromachining, and the like. It’s not merely an essential Device for people today to investigate the earth, but also a pillar area of laser know-how. This evaluate existing the technology of femtosecond pulses in ultrafast method-locked fiber lasers applying Lively, passive, hybrid mode-locking tactics, the emphasis is provided to passively mode-locked fiber lasers. Regarding the optimization of femtosecond pulses, we introduce the external compression approach to acquire shorter pulse width, chirped pulse amplification method to extend pulse Power and acquire substantial Electrical power femtosecond pulses at the sensible band.
A method is produced to resolve the process of shortened equations describing parametric technology inside a 1-frequency OPO cavity beneath nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe two, and HgGa2S4 crystals plus the exceptional reflection coefficient of the output mirror are estimated versus the pump energy density Wp at distinct values in the OPO nonstationarity .
The precise warmth and thermal conductivity of HgGa2S4 are measured. It is concluded which the combined properties of HgGa2S4 crystals can offer for them a number one posture Amongst the supplies Utilized in nonlinear-optical units for mid-IR-frequency conversion.
The engineering of developing mercury thiogallate crystals (HgGa2S4) is improved and higher-high quality bulk samples are manufactured. The essential optical and thermal Houses of those crystals are studied. The transmission spectra of mercury thiogallate are measured and its nonlinear properties like the quadratic susceptibility, tuning curves, along with the optical-harm resistance are also identified.
... The very first facts around the refractive index of orange HGS released by Levine et al. [35] included only handful of wavelengths from the visible and around-IR equally as an indication on the feasibility of the crystal for birefringent section-matching. The refractive indices for the orange phase had been measured and tabulated among 0.
to the detection of molecular trace gasses. The oscillation threshold, output electric power and stability of The one resonant
A pulsed TEA CO2 laser was employed to research the impact of pump radiation parameters (mode structure, wavelength, and pulse period), concentrating problems, absorption coefficient, and temperature within the efficiency of conversion into the 2nd harmonic and on angular dependences of section matching in ZnGeP2 crystals. Very good arrangement betweeen experimental and theoretical outcomes is noticed. Examine extra
Change frequency mixing of strongly concentrated Gaussian beams in periodically poled LiNbO3 was investigated. The beams were focused In the crystal get more info with out injury. Mixing of cw and pulsed laser programs was utilized to reduce the thermal lensing outcomes within this crystal. A minimal-electricity cw 1.064‐μm Nd:YAG laser beam was employed as being the pump, While the signal beam arrived from the picosecond optical .
