Oxides and chalcopyrites semiconductor materials have infrared laser properties noticed in the infrared region, but their application was restricted due to their disadvantages. So CsGeCl3 has been studied because of its very wide-band transparency range and higher nonlinear optical coefficients. This letter will report on the crystal growth and properties of CsGeCl3. Transparent crystals have been grown from a HCl-EtOH-CsCl mixture solution and its transparency region was found to be up to 20 mu m. It has no congruent melting point and it decomposes at 325 degrees C. Powder double-frequency studies show that its SHG signal was about 5 times to that of KDP and damage threshold was up to 200 M W/cm(2). These results show that CsGeCl3 is a potential material for frequency-doubling application in the infrared region.
