With the advent of recent nonlinear components and one-frequency pump resources, There's renewed curiosity in optical parametric oscillators (OPOs). A single-mode diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is certainly both equally amplified and frequency doubled is used to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
A manner-locked tunable dye laser continues to be developed which is synchronously pumped at large repetition fees with the doubled output of a method-locked Nd:YAG laser. The dye laser gives rigorous pulses of 35 psec duration that are commonly tunable, of around-change-restricted bandwidth, As well as in time coincidence Along with the pumping pulses.
Aside from the compactness and benign working features, it had been the big flexibility in design and style and output features that led to the accomplishment of sound-condition lasers over the past 40 a long time.
An easy strategy for reducing the loss that is because of depolarization ensuing from thermally induced tension birefringence in solid-state lasers is noted. The method works by using a single intracavity quarter-wave plate with its fast or gradual axis aligned parallel to the popular plane of polarization, described by an intracavity polarizer.
We report new experimental effects on the phase-matching Homes of yellow coloration HgGa2S4 crystals for harmonic generation of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers from the 0.944-10.5910 μm vary. Also, we existing new Sellmeier equations that supply a superior copy of your current experimental benefits together with the printed information factors for next-harmonic era of CO2 laser radiation at 9.
The significant conversion performance and big selection of radiation wavelength tuning makes it possible for to assume this content could compete with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals Despite the check here substantial issues of massive sizing crystals expansion procedure.
Optical Houses of orange phased HgGa2S4 crystal is investigated. Technology of tunable middle infrared radiation by next harmonic of tunable CO2 laser radiation is demonstrated. Second harmonic conversion efficiency with respect to other infrared crystal has also been discussed.

The specific warmth and thermal conductivity of HgGa2S4 are measured. It can be concluded which the combined properties of HgGa2S4 crystals can offer for them a leading placement Among the many resources Utilized in nonlinear-optical devices for mid-IR-frequency conversion.
Examination of recent, promising extensive-band-gap nonlinear crystals for that mid-IR is given. We centered on ternary and quaternary chalcogenides and based mostly on their physical and chemical Attributes, which In combination with linear and nonlinear optical Houses, establish the performance of crystal usage in sure laser experiments. The correlation amongst the composition, structure and output parameters and also the developments in adjustments of the most crucial attributes such as band gap, nonlinear susceptibility, laser hurt threshold, etcetera, are shown.
The defect chalcopyrite crystal HgGa2S4 has long been utilized inside of a 1064-nm pumped optical parametric oscillator to generate Nonlinear crystals for optical parametric oscillators pumped by light-weight pulses of in the vicinity of IR lasers...
Be aware: Writer names are going to be searched within the key terms subject, also, but that will come across papers wherever the person is talked about, instead of papers they authored.
In this particular paper we theoretically look into probably the most economical pump temporal shape for pulsed operation of optical parametric oscillators (OPOs). The theoretical Investigation includes solving the best Handle dilemma utilizing the rate equation formalism. The OPO optimal buildup conduct is derived for virtually any OPO configuration, and we present which the optimum pump pulse shape can be a double rectangle. The very first rectangle is optimized for that buildup approach, even though the 2nd a single is optimized for the regular condition, and both equally depend otherwise over the OPO mirror reflectivities together with the accessible pump Strength and utmost peak electric power.
Tunable mid-IR radiation is attained all through 2nd harmonic era of tunable CO2-laser radiation employing a CdGeAs2 crystal. Its angular tuning features within the CO2- laser wavelength, angular acceptance angle and spectral acceptance are calculated.
