With the advent of recent nonlinear products and solitary-frequency pump resources, there is renewed fascination in optical parametric oscillators (OPOs). Only one-mode diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is definitely both equally amplified and frequency doubled is accustomed to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
We report over a femtosecond optical parametric oscillator (OPO) for that deep-infrared (deep-IR) based on the Kerr-lens-mode-locked Ti:sapphire laser as being the pump source. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO based on the nonlinear crystal, CdSiP 2 , synchronously pumped interior to some MgO:PPLN femtosecond OPO, We now have created broadly tunable radiation throughout 5958�?117 nm using fast static cavity hold off tuning, using a maximum energy of 64 μW at 6791 nm, restricted through the absorption in mirror substrates in addition to polarization-dependent intracavity losses.
The main-principles density functional calculations are performed to study the geometries and Digital buildings of HgGa2X4 (X = S, Se, Te) semiconductors with defect chalcopyrite constructions, along with the optical Homes of all crystals are investigated systematically. The outcomes indicate that these compounds have very similar band structures and also the band hole decreases from S to Se to Te. For the linear optical Attributes, a few crystals demonstrate very good light transmission during the IR and element obvious regions, and particularly, HgGa2S4 and HgGa2Se4 crystals have moderate birefringence.
.. [Present comprehensive abstract] third-harmonic technology and parametric amplification with small-frequency pumping in periodically poled Energetic nonlinear crystals are investigated. The Assessment is carried out for the situation of the periodically poled Nd:Mg:LiNbO3 crystal. Perspectives of using periodically poled active nonlinear crystals in laser units with self-frequency conversion are discussed.
We report new experimental benefits about the phase-matching properties of yellow shade HgGa2S4 crystals for harmonic technology of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers while in the 0.944-ten.5910 μm assortment. Furthermore, we existing new Sellmeier equations that give a excellent reproduction in the current experimental results plus the printed data points for 2nd-harmonic generation of CO2 laser check here radiation at 9.
PA Ref-mobile, which substantially cuts down themeasurement errors from the methane concentration in thecase of instability
Two parametric 4-wave-mixing (FWM) processes in Rb atoms are researched utilizing perturbation theory underneath the issue of rotating wave approximation. The two parametric FWM procedures are coupled when they are excited coherently by a brief laser pulse by using a bandwidth encompassing The 2 corresponding upper Vitality stages in the two FWM processes.
Determined by the theories of period matching and suitable composition ratio, the affect of composition ratio around the frequency conversions of two varieties (phases) of Cd doped Hg1-xCdxGa2S4 was investigated. In consideration of corresponding sellmeier equations, section matching diagrams of next harmonic generation and optical parametric oscillations pumped by the popular Nd3+:YAG and Ho3+:YLF lasers were calculated, and acceptable composition ratios with many compositions.
Also, we executed a numerical simulation of chirped-pulse OPOs (CPOPOs) and revealed that the spectral profile of the output from a CPOPO was related to each the parametric obtain profile in the nonlinear crystal along with the intra-cavity substantial-purchase dispersion.
This paper testimonials the modern developments in crystal expansion and singly resonant optical parametric oscillators to the generation of higher one pulse Electricity and regular powers inside the mid-IR from 3 to ten μm.
Interference is noticed in between the spontaneous parametric radiation from two nonlinear crystals separated by a macroscopic
The noticed file -to- 2 file frequency beats, originating directly from the OPO, can be utilized for self-referencing and phase locking on the pump laser comb with no need for supercontinuum era. With an average output electric power of �?30 mW , this set up may be effective for various spectroscopic purposes inside the mid-IR.
