and functioning circumstances for the sensible design of superior ability femtosecond optical parametric oscillators with excitation
A person observes a spectacular increase in generation of the 2nd harmonic as well as the demodulation indicators versus the pump wave amplitude. A clear correlation exists between these nonlinear signatures and the quantity of damages. Preliminary determinations on the coefficient of quadratic nonlinearity are already achieved. The effects while in the configuration of parametric emitting antenna are believed to become the really very first on cracked supplies.
Moreover the compactness and benign functioning functions, it had been the enormous versatility in style and output traits that led on the success of stable-state lasers over the past 40 many years.
.. [Display total summary] 3rd-harmonic generation and parametric amplification with low-frequency pumping in periodically poled Energetic nonlinear crystals are also investigated. The Evaluation is performed for the situation of the periodically poled Nd:Mg:LiNbO3 crystal. Perspectives of applying periodically poled Lively nonlinear crystals in laser devices with self-frequency conversion are discussed.
We report new experimental effects about the period-matching Homes of yellow color 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 vary. Furthermore, we existing new Sellmeier equations that provide a excellent replica with the present experimental effects along with the posted info details for next-harmonic technology of CO2 laser get more info radiation at nine.
The significant conversion effectiveness and wide range of radiation wavelength tuning permits to anticipate this substance may well compete with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals Despite the substantial difficulty of big dimensions crystals advancement process.
The temperature dependence of refractive indices of optical supplies is characterized During this operate by what we contact their normalized thermo-optic coefficients. These are definitely determined experimentally by way of interferometric measurements of thermal enlargement and of changes in optical thickness at a couple of laser wavelengths as perform of temperature. A suitable vectorial formalism applied to these information enables predicting the thermal evolution from the refractive index all around the handy variety of transparency.
Pumping mid-IR optical parametric oscillators around one μm is appealing for its simplicity and electrical power scaling functionality. To this aim, large bandgap non-oxide nonlinear crystals are wanted.

The 3rd harmonic of CO2-laser radiation has become acquired by passing the laser beam by way of two CdGeAs2 crystals in tandem, with the main crystal oriented for 2nd-harmonic technology and the next for sum mixing. Applying this technique, We've got reached an average exterior conversion effectiveness of one.
... The main knowledge on the refractive index of orange HGS revealed by Levine et al. [35] incorporated only handful of wavelengths inside the noticeable and around-IR equally as a demonstration in the feasibility of the crystal for birefringent phase-matching. The refractive indices for your orange period ended up calculated and tabulated amongst 0.
for the detection of molecular trace gasses. The oscillation threshold, output electric power and stability of The only resonant
A simple quantum product agrees perfectly While using the experimental success and causes it to be achievable to interpret the impact in terms of
This is the first illustration of a broadband OPO working through the molecular fingerprint region, and we demonstrate its probable by conducting broadband Fourier-remodel spectroscopy applying water vapor and also a polystyrene reference regular.
