AOLF615-1049
Acousto-Optic Line Filter
SOLID STATE
FAST ACCESS TIME
MINIMAL CHROMATIC DEFLECTION
The AOLF range of acousto-optic tuneable (line) filters are specifically designed for use with laser sources.
The wavelength of the diffracted light is selected according to the frequency of the RF drive signal. Isomet grown tellurium dioxide (Te02), which has been oriented for off-axis mode operation, is utilised as the interaction material. Fast access times and fine spectral bandwidths make these filters ideal for selecting discrete lines from a multi-line laser sources.
For horizontal input polarization, the crystal geometry is designed to minimize chromatic beam deflection of the +1st output.
Suitable electronics include the Isomet iSPA-MF4 frequency synthesizer / power amplifier
Fibre coupling option is available.
