Аннотация: Using a nonlinear photonic crystal (NPC) of strontium tetraborate, we obtained the second-harmonic generation of femtosecond pulses in the nonlinear diffraction regime with an efficiency of 1.9% that is tunable in the near-UV spectral range, as well as fourth-harmonic generation under the conditions of random quasi-phase-matching wПоказать полностьюith maximum efficiency of 10(-5) that is tunable in the far-UV spectral range. The efficiency of second-harmonic generation in strontium tetraborate NPC under the conditions of random quasi-phase-matching was significantly lower. The fourth-harmonic was tunable between 187.5 and 232.5 nm. The previously predicted red shift of spectral components in the generated radiation spectrum upon NPC rotation is demonstrated experimentally.
