摘要
Abstract
Single crystals of CdSe were grown by using seeded oriented temperature gradient solution zoning (STGSZ) method with the sizes of 20 mm in diameter and 80 mm in length. The crystals were characterized with X-ray diffraction, transmission spectrophotometer and infrared microscope. The transmission spectra showed that the infrared transmission is above 65% and the mean absorption was 0.01-0.04 cm-1 in the range of 2.5-20 μm. With 2.797 μm Cr,Er:YSGG laser as pumping source, experiments of optical parametric oscillator (OPO) were performed by using fabricated 5 mm×5mm×30 mm device crystal. The signal and idler wavelengths and the output average power were respectively 4.3 μm, 8 μm and 400 μJ. Optical-to-optical conversion efficiency was obtained by 12%.
