M1142-SF80L-0.5
Acousto-Optic Modulator
The M1142 is low dispersion Glass AOM designed primarily for Ti:Sapphire laser applications.
This model offers a good compromise between diffraction efficiency and pulse stretching characteristics. If should be noted that the high RF drive power dissipation resulting from CW operation in the NIR will cause some output beam drift. An alternative model is the M1133-aQ80-1 which is more suited to variable duty cycle and CW operation.
