and functioning problems for the sensible style of significant power femtosecond optical parametric oscillators with excitation
Outcomes of thermal conductivity measurements are reported for quite a few of the more lately created nonlinear optical crystals. New or significantly revised values of thermal conductivity had been attained in six elements. Noteworthy thermal conductivities measured were being People for AgGaS2 [0.014 W/(cm K) and 0.
crystals with ultrafast Yb-ion laser pump is proposed. The final results form a valuable reference for the selection of supplies
The higher conversion effectiveness and wide range of radiation wavelength tuning will allow to be expecting that this content may possibly contend with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals Regardless of the sizeable issue of massive dimensions crystals expansion approach.
On top of that, the coherent beam blend and divided pulse amplification system to further Improve pulse Strength are summarized. At the conclusion of this assessment, we current an in depth overview of your programs of femtosecond pulses such as the technology of supercontinuum and tunable femtosecond pulses, and a few realistic purposes. A number of perspectives and research directions of femtosecond pulses can also be resolved.
The significant conversion performance and wide range of radiation wavelength tuning permits to be expecting this substance may possibly compete with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals Regardless of the considerable problems of big dimension crystals development approach.
Two parametric four-wave-mixing (FWM) processes in Rb atoms are analyzed making use of perturbation idea underneath the issue of rotating wave approximation. The 2 parametric FWM processes are coupled when they are fired up coherently by a brief laser pulse with a bandwidth encompassing The 2 corresponding higher Power stages in The 2 FWM procedures.
Depending on the theories of phase matching and suitable composition ratio, the impact of composition ratio to the frequency conversions of two sorts (phases) of Cd doped Hg1-xCdxGa2S4 was investigated. In thing to consider of corresponding sellmeier equations, phase matching diagrams of 2nd harmonic generation and optical parametric oscillations pumped by the popular Nd3+:YAG and Ho3+:YLF lasers ended up calculated, as well as acceptable composition ratios with different compositions.
The particular heat and thermal conductivity of HgGa2S4 are measured. It really is concluded the put together Attributes of HgGa2S4 crystals can offer for them a number one situation Among the many elements used in nonlinear-optical devices for mid-IR-frequency conversion.
The 3rd harmonic of CO2-laser radiation has become obtained by passing the laser beam as a result of two CdGeAs2 crystals in tandem, with the primary crystal oriented for second-harmonic technology and the 2nd for sum mixing. Employing this technique, we have obtained an average exterior conversion performance of 1.
... The initial knowledge on the refractive index of orange HGS revealed by Levine et al. [35] included only number of wavelengths during the visible and close to-IR just as an illustration on the feasibility of the crystal for birefringent period-matching. The refractive indices with the orange phase have been calculated and tabulated involving click here 0.
Take note: Author names will probably be searched from the search phrases discipline, also, but that could obtain papers where by the individual is pointed out, rather than papers they authored.
A pulsed TEA CO2 laser was employed to research the result of pump radiation parameters (method framework, wavelength, and pulse duration), concentrating disorders, absorption coefficient, and temperature on 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 final results is observed. Examine far more
Big difference frequency mixing of strongly concentrated Gaussian beams in periodically poled LiNbO3 was investigated. The beams ended up concentrated inside the crystal without injury. Mixing of cw and pulsed laser devices was used to attenuate the thermal lensing effects inside this crystal. A reduced-electricity cw one.064‐μm Nd:YAG laser beam was applied given that the pump, Whilst the sign beam arrived from a picosecond optical .
