Fast-response pyroelectric crystal detector based on Ba0.25Sr0.75Nb2O6 V. V. Voronov, N. V. Karlov, G. P. Kuz'min, Yu. S. Kuz'minov, B. A. Kuritsyn, S. M. Nikiforov, V. V. Osiko, A. M. Prokhorov Abstract: A study was made of the problems of using BaxSr1–xNb2O6 (BSN) crystals to measure high-power CO2 laser radiation of λ = 10.6 μ wavelength. An experimental investigation of BSN crystals with x = 0.25 yielded the characteristics of a pyroelectric detector of this type: responsivity 20 V/MW; response time 2 nsec; linear up to 3 MW/cm2; optical strength up to 9 MW/cm2. Pyroelectric detectors based on BSN crystals were used to detect and analyze the spatial and temporal structure of short high-power CO2 laser pulses.  Full text:
