CaMoO4 ELECTRONICALLY TUNABLE OPTICAL FILTER

The paper describes a CaMoO4 transmission‐type acousto‐optic filter. Tuning from about 6700 to 5100 A is obtained by changing an acoustic frequency from 40 to 68 MHz. The filter bandwidth is 8 A at an f/6 aperture. 95% transmission is obtained at an acoustic power density of 69 mW/mm2.
