The ultra-broadband stage matching was experimentally observed inside a DKDP crystal upon parametric amplification of signal radiation
The idea of laser-induced injury in DKDP crystal helps you to improve the crystal excellent within the processes of advancement and fabrication, which have been proved by the improvement on laser-induced problems thresholds (LIDT) in the last a long time. Having said that, the mechanism of LID for THG DKDP crystals is not really totally understood nevertheless as well as LIDT of DKDP crystals ought to be even more improved with the event of high energy laser devices.
Remarkably-deuterated potassium dihydrogen phosphate (DKDP) crystals ended up grown swiftly from level seeds below higher supersaturation in the temperature variety of 40-60 °C. The expansion amount was about 1-two purchase of magnitude higher than that of the traditional temperature reduction approach. It was uncovered that hugely pure raw components, overheating at high temperature, ultrafine filtration and supersaturation security have been required to hold the answer from spontaneous nucleation at superior overcooling.
Investigation of bulk laser problems in KDP crystal as a perform of laser irradiation path, polarization, and wavelength
longitudinal electro-optical result in crystal of DKDP was applied and its size was Φ10mm ×
Aspects including mechanical deformation and temperature alterations bring on stage mismatch in optical parametric amplification techniques, impacting Vitality steadiness. A period compensation technique by using the linear electro-optic influence can defeat this limitation. Phase mismatch payment attributes had been simulated via the linear electro-optic influence in 70%-deuterated DKDP and 95%-deuterated DKDP. This technique was applied to OPA programs to verify its feasibility.
The angular dependance with the transverse Raman scattering in potassium dihydrogen phosphate (KDP) and its deuterated analogue (DKDP) for the entire choice of crystal configurations suitable for laser beam polarization Management has been investigated through experimental and modeling tools. This operate was built probable by concurrently rotating a spherical sample and the pump polarization to efficiently measure the angular dependance on the transverse Raman signal in 360°. This novel strategy, and that is relevant for that investigation with the Raman scattering in optically anisotropic products, demonstrates which the spontaneous Raman scattering sign reveals powerful angular dependence that's modulated by depolarization and polarization rotation effects created as the Raman signal traverses the material because of its birefringence.
