GaSe crystals for IR and terahertz generation: fabricating large-aperture nonlinear optical elements and protective and antireflective coatings
摘要
Some physical and technological conditions for the growth of large GaSe crystals by the Bridgman method and the calculated and experimentally measured parameters of the samples coated with SiO2 antireflective films are presented. The fabricated nonlinear optical elements have certain advantages for generating IR and terahertz radiation via nonlinear frequency conversion.
