With the arrival of latest nonlinear elements and one-frequency pump resources, There's renewed desire in optical parametric oscillators (OPOs). A single-manner diode-laser-pumped monolithic Nd:YAG nonplanar ring laser which is both amplified and frequency doubled is accustomed to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
We report on the femtosecond optical parametric oscillator (OPO) for that deep-infrared (deep-IR) dependant on the Kerr-lens-mode-locked Ti:sapphire laser because the pump supply. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO based upon the nonlinear crystal, CdSiP two , synchronously pumped interior to the MgO:PPLN femtosecond OPO, We've generated broadly tunable radiation across 5958�?117 nm utilizing speedy static cavity delay tuning, using a most energy of 64 μW at 6791 nm, confined with the absorption in mirror substrates and also polarization-dependent intracavity losses.
A list of ~450 noncentrosymmetric sulfides is observed in reference to nonlinear optical Houses. It has been found that about the airplane with the oxide bond lengths the noncentrosymmetric sulfide crystals are dominantly positioned into a rosette of two intersected ellipses of «acentricity».
The concept of chemical transport reactions (volatilization of a cloth by way of a very low-volatile chemical intermediate in a temperature T1 and back-response with the mixture at a temperature T2, utilizing the temperature dependence from the chemical equilibrium concerned) is usually a useful Software for escalating single crystals of numerous materials which can not be effortlessly received within the soften.
We report new experimental benefits around the section-matching Homes of yellow coloration HgGa2S4 crystals for harmonic era of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers in the 0.944-ten.5910 μm variety. On top of that, we present new Sellmeier equations that offer a excellent reproduction with the present experimental success together with the revealed facts points for next-harmonic generation of CO2 laser radiation at 9.
The calculated core amount binding energies are when compared with Individuals of HgS, GaS, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves to become unbiased within the technological situations of crystal advancement. In distinction to the valence band spectrum, the distribution of electron states within the bandgap of HgGa2S4 crystals is discovered to generally be strongly dependent on the technological situations of crystal development as shown by the photoluminescence Examination.
Two parametric 4-wave-mixing (FWM) procedures in Rb atoms are analyzed working with perturbation idea underneath the issue of rotating wave approximation. The 2 parametric FWM procedures are coupled when they are enthusiastic coherently by a short laser pulse with a bandwidth encompassing The 2 corresponding upper Vitality stages in The 2 FWM processes.

In addition, we carried out a numerical simulation of chirped-pulse OPOs (CPOPOs) and exposed that the spectral profile of the output from the CPOPO was applicable to both equally the parametric get profile with the nonlinear crystal plus the intra-cavity substantial-purchase dispersion.
The third harmonic of CO2-laser radiation has become received by passing the laser beam by way of two CdGeAs2 crystals in tandem, with the primary crystal oriented for second-harmonic era and the 2nd for sum mixing. Making use of this technique, We now have achieved a median exterior conversion effectiveness of 1.
Simple technique for minimizing the depolarization reduction ensuing from thermally induced birefringence in solid-condition lasers
The noticed f -to- 2 file frequency beats, originating directly from the OPO, can be used for self-referencing and period locking from the pump laser comb without having for supercontinuum era. With a mean output electric power of �?30 mW , this setup more info may very well be helpful for various spectroscopic purposes while in the mid-IR.
A pulsed TEA CO2 laser was employed to research the impact of pump radiation parameters (manner framework, wavelength, and pulse length), focusing disorders, absorption coefficient, and temperature to the effectiveness of conversion into the 2nd harmonic and on angular dependences of phase matching in ZnGeP2 crystals. Fantastic arrangement betweeen experimental and theoretical effects is noticed. Browse much more
three% rms over 12 h in superior beam top quality. The in the vicinity of-IR signal pulses with the OPO have a Gaussian pulse length of �?19 ps , calculated at 1284 nm. We have investigated the temperature tuning attributes of your OPO and in contrast the information with the theoretical calculations making use of The latest Sellmeier equations and thermo-optic coefficients with the crystal. To the very best of our expertise, Here is the first picosecond OPO based on CSP operating at MHz repetition prices.
