.. [Show comprehensive summary] parametric oscillator. The two independently centered beams had been built to overlap inside the crystal. The concentrating parameters of the two beams had been with regards to the exact. The focusing functionality formulated by Boyd and Kleinman for tightly targeted beams was extended to periodically poled crystals as a way to suit the temperature-tuning curve. A 0.66%/W effectiveness was attained for the difference frequency mixing course of action.
Output idler energies within the microjoule level are attained with utmost conversion effectiveness of eleven% to the amplifier phase, which can be greater than two periods better than the outcome attained with the analogous sample in the commonly distribute content AgGaS two .
This technique makes it possible for the Procedure of greatly tunable optical parametric oscillators2 (OPO) and subsequent change frequency generators3 manufacturing tunable pulses of large peak power. The higher energy in the pump pulse trains has specified Advantages for your operation of the synchronously pumped OPO, e.g., peaceful balance needs, and also the probable to work with significant cavity losses (e.g. metallic mirrors) enabling huge tuning ranges with only one set of mirrors and superior output-coupling variables for pulse shortening.
The significant conversion efficiency and wide range of radiation wavelength tuning lets to assume that this content may well contend with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals in spite of the substantial issues of huge sizing crystals growth procedure.
In this do the job, we existing precisely what is, to our know-how, the 1st measurements from the quantum section diffusion noise of the cw OPO. Examine much more
We report the implementation of the KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Including sign and idler, it may be repeatedly tuned from 1.261 via 2.532 μm by varying the pump wavelength. Two significant advancements ended up reached, including the relationship with the signal and idler tuning ranges and also the high output pulse Electrical power throughout the sign and idler tuning ... [Exhibit total summary] ranges. The primary improvement was realized by finding two individual sets of period-matching angles. The second enhancement was understood by using five sets of resonator mirrors for oscillating possibly signal or idler.
Ultrafast femtosecond mode-locked fiber laser plays an indispensable function in medical imaging, Place ranging, ophthalmology, terahertz spectroscopy, material micromachining, and so forth. It’s not just a very important Instrument for people today to discover the world, but in addition a pillar industry of laser technological innovation. This assessment present more info the technology of femtosecond pulses in ultrafast method-locked fiber lasers applying Energetic, passive, hybrid method-locking tactics, the emphasis is presented to passively manner-locked fiber lasers. When it comes to the optimization of femtosecond pulses, we introduce the external compression technique to obtain shorter pulse width, chirped pulse amplification strategy to raise pulse Electricity and acquire superior energy femtosecond pulses at the sensible band.
Based on the theories of stage matching and suitable composition ratio, the impact of composition ratio within the frequency conversions of two kinds (phases) of Cd doped Hg1-xCdxGa2S4 was investigated. In thought of corresponding sellmeier equations, period matching diagrams of next harmonic technology and optical parametric oscillations pumped by the popular Nd3+:YAG and Ho3+:YLF lasers have been calculated, together with appropriate composition ratios with different compositions.
The particular heat and thermal conductivity of HgGa2S4 are measured. It is concluded that the combined Homes of HgGa2S4 crystals can offer for them a number one posture among the elements used in nonlinear-optical equipment for mid-IR-frequency conversion.

... The first knowledge on the refractive index of orange HGS published by Levine et al. [35] involved only couple of wavelengths while in the seen and near-IR just as a demonstration in the feasibility of this crystal for birefringent stage-matching. The refractive indices for that orange period ended up measured and tabulated amongst 0.
for your detection of molecular trace gasses. The oscillation threshold, output electricity and security of The only resonant
An easy quantum product agrees perfectly Along with the experimental final results and can make it probable to interpret the influence regarding
Distinction frequency mixing of strongly targeted Gaussian beams in periodically poled LiNbO3 was investigated. The beams have been centered Within the crystal devoid of problems. Mixing of cw and pulsed laser programs was utilized to reduce the thermal lensing results within this crystal. A minimal-electricity cw one.064‐μm Nd:YAG laser beam was utilised given that the pump, Whilst the sign beam came from a picosecond optical .
