Strong-State Laser Engineering is penned from an industrialperspective and discusses in detail the qualities, design, construction and practical problems of sound-statelasers. Emphasis is placed on engineering and practicalconsiderations, which has a phenomenological treatment usingmodelsbeing favored to summary mathematical derivations.
Output idler energies over the microjoule amount are received with maximum conversion performance of eleven% for your amplifier phase, which happens to be in excess of two moments a lot better than the outcomes received having an analogous sample on the greatly spread material AgGaS two .
This system permits the operation of extensively tunable optical parametric oscillators2 (OPO) and subsequent difference frequency generators3 producing tunable pulses of substantial peak electric power. The higher Vitality from the pump pulse trains has selected Rewards to the Procedure of the synchronously pumped OPO, e.g., peaceful steadiness needs, plus the opportunity to operate with significant cavity losses (e.g. metal mirrors) permitting massive tuning ranges with a single list of mirrors and large output-coupling aspects for pulse shortening.
.. [Exhibit full summary] third-harmonic technology and parametric amplification with very low-frequency pumping in periodically poled active nonlinear crystals are investigated. The Examination is carried out for the case of a periodically poled Nd:Mg:LiNbO3 crystal. Views of working with periodically poled active nonlinear crystals in laser units with self-frequency conversion are reviewed.
We report new experimental effects on the section-matching properties of yellow color HgGa2S4 crystals for harmonic technology of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers within the 0.944-10.5910 μm vary. Furthermore, we present new Sellmeier equations that offer a fantastic reproduction in the existing experimental benefits as well as the released data factors for 2nd-harmonic era of CO2 laser radiation at nine.
The measured Main level binding energies are when compared with Individuals of HgS, GaS, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves to generally be impartial within the technological disorders of crystal development. In contrast to your valence band spectrum, the distribution of electron states inside the bandgap of HgGa2S4 crystals is identified for being strongly dependent on the technological situations of crystal development as demonstrated via the photoluminescence Examination.
The temperature dependence of refractive indices of optical supplies is characterized With this get the job done by what we simply call their normalized thermo-optic coefficients. These are generally determined experimentally through interferometric measurements of thermal enlargement and of improvements in optical thickness at a couple of laser wavelengths as perform of temperature. An appropriate vectorial formalism placed on these facts permits predicting the thermal evolution of the refractive index all around the beneficial variety of transparency.
This new version has actually been up-to-date and revised to includeimportant developments, principles and technologies that haveemerged For the reason that publication of the primary version.
The specific warmth and thermal conductivity of HgGa2S4 are measured. It's concluded which the combined Homes of HgGa2S4 crystals can provide for them a leading posture One of the supplies read more used in nonlinear-optical units for mid-IR-frequency conversion.

... The 1st information around the refractive index of orange HGS revealed by Levine et al. [35] included only couple of wavelengths while in the noticeable and in close proximity to-IR equally as a demonstration on the feasibility of this crystal for birefringent stage-matching. The refractive indices for the orange stage were measured and tabulated between 0.
twelve μm and explain all frequency conversion schemes realized up to now with them and upcoming opportunity applications. Key phrases: Ternary and quaternary semiconductors, defect chalcopyrites, stable methods, nonlinear optical crystals, mid-infrared
With this paper we theoretically examine the most successful pump temporal form for pulsed operation of optical parametric oscillators (OPOs). The theoretical Assessment contains solving the optimal control trouble using the rate equation formalism. The OPO best buildup behavior is derived for virtually any OPO configuration, and we display the ideal pump pulse form is really a double rectangle. The very first rectangle is optimized with the buildup course of action, although the next a single is optimized with the continuous state, and both rely in another way to the OPO mirror reflectivities as well as the out there pump Electrical power and maximum peak energy.
Tunable mid-IR radiation is received for the duration of 2nd harmonic era of tunable CO2-laser radiation utilizing a CdGeAs2 crystal. Its angular tuning traits at the CO2- laser wavelength, angular acceptance angle and spectral acceptance are measured.
