AOTF614-xx AO
Tuneable Filter
- SOLID STATE -FAST ACCESS TIME
The AOTF range of acousto-optic devices are solid state optical filters. 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. The best diffraction efficiency is obtained with linearly polarised input light.
Suitable electronics include the iSPA-SF1 series of frequency synthesizer RF driver/amplifiers
Note: The drive frequency for any given AOTF is limited to a maximum RF tuning range of one octave (2:1) within the overall range shown in the tables overleaf.
This is illustrated by the three examples, ‘A’,’B’,’C’, highlighted by the coloured bands.
