053 μm. The absorption spectrum of ammonia was offered to exhibit the feasibility of the developed optical parametric oscillator procedure for spectroscopic measurements and gasoline detection.

A mode-locked tunable dye laser has been created that is synchronously pumped at large repetition premiums from the doubled output of the method-locked Nd:YAG laser. The dye laser offers intense pulses of 35 psec duration that are extensively tunable, of near-transform-constrained bandwidth, As well as in time coincidence Together with the pumping pulses.

.. [Show comprehensive summary] 3rd-harmonic technology and parametric amplification with small-frequency pumping in periodically poled active nonlinear crystals will also be investigated. The Investigation is completed for the case of a periodically poled Nd:Mg:LiNbO3 crystal. Perspectives of utilizing periodically poled Lively nonlinear crystals in laser products with self-frequency conversion are reviewed.

We report new experimental outcomes on the stage-matching properties of yellow color HgGa2S4 crystals for harmonic generation of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers inside the 0.944-ten.5910 μm assortment. In addition, we current new Sellmeier equations that provide a good copy of the existing experimental outcomes in addition to the released information points for second-harmonic era of CO2 laser radiation at nine.

The high conversion performance and wide selection of radiation wavelength tuning makes it possible for to count on this content may compete with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals Regardless of the sizeable problems of huge size crystals advancement procedure.

Two parametric 4-wave-mixing (FWM) procedures in Rb atoms are studied working with perturbation principle beneath the ailment of rotating wave approximation. The two parametric FWM procedures are coupled when they are thrilled coherently by a brief laser pulse having a bandwidth encompassing The 2 corresponding upper Electrical power degrees in the two FWM procedures.

This new edition has long been up-to-date and revised to includeimportant developments, concepts and technologies that haveemerged Considering that the publication of the first version.

The specific heat and thermal conductivity of HgGa2S4 are measured. It is actually concluded the put together Qualities of HgGa2S4 crystals can offer for them a leading position Amongst the resources used in nonlinear-optical equipment for mid-IR-frequency conversion.

The third harmonic of CO2-laser radiation has long been acquired by passing the laser beam as a result of two CdGeAs2 crystals in tandem, with the primary crystal oriented for 2nd-harmonic technology and the second for sum mixing. Applying this technique, Now we have obtained a mean exterior conversion effectiveness of one.

Basic technique for cutting down the depolarization decline ensuing from thermally induced birefringence in solid-condition lasers

Quantum mechanical based 1st principle calculations have already been utilized to acquire the more info device mobile lattice parameters of mercury thiogallate (HgGa2S4) in defect stannite framework for The 1st time. For this, we handled HgGa2S4 in two differing kinds of website symmetries in a similar Area group.

Mid-IR next-order NLO crystal is indispensable within the frequency conversion apps from the mid-IR area. In contrast with DUV and UV/Vis/close to-IR NLO crystals, functional mid-IR NLO crystals are rather scarce, and many of these are still with the stage of laboratory investigate. This chapter evaluations the the latest development to the mid-IR NLO crystals, which generally consists of rising the classical mid-IR NLO crystals into massive significant-good quality types or into quasi-period-matching constructions that are well suited for the laser products by a variety of progress techniques and exploring new probable mid-IR NLO crystals by introducing new design and synthesis tactics.

Diode-pumped optical parametric oscillation has actually been demonstrated for the first time to our awareness in an individual Nd:MgO:LiNbO3 nonlinear crystal. The crystal is pumped by a semiconductor diode laser array at 812 nm. The Nd³�?ions take up the 812-nm radiation to create 1084-nm laser oscillation.
