The H-101 from L3Harris Technologies is a Silicon Dioxide (SiO2) Acousto-Optic Modulator that operates at a wavelength of 514.5 nm. It has a modulation bandwidth above 100 MHz and center frequency of 380 MHz. This AOM has an optical polarization perpendicular to acoustic axis and a rise time of less than 8 ns. It has a maximum average/peak drive power of 1W/10W for 1 ms and single pass diffraction efficiency greater than 10 % at 500 mW drive power. This brewster windowed AOM has a nominal input impedance of 50 Ohms and static contrast ratio above 500:1.
The H-101 has a beam diameter of 40 mm and beam distance of 0.5 mm from the transducer. It has a maximum diffraction efficiency of 72 % and diffracted beam ellipticity of 1.43. This AOM is ideal for an electrically controlled optical switch for selecting a single pulse out of a pulse train, Intracavity use in conjunction with mode locker to increase the energy of a single pulse or select ultrashort pulses, General-purpose, and high-speed modulation applications.
