| Abstract: | With Ge signle crystal as a media for acousto optic mutual action,an acousto optic switch device for CO 2 laser has been developed.Light absorption phenomena appeared in Ge acousto optic device and its relation with temperature especially the heat source caused by transducer loss are discussed in the paper.The relation between the absorption coefficient of Ge with different resistivity values and temperature under the constant light power and the relation between the absorption light power of Ge and temperature under the different light powers are also discussed. |
