770nm Free Space Acousto-optic Frequency Shifter AOFS

770nm Compact AOM Free Space Frequency Shift.

Compact AOM to shift laser wavelength peridically.

Frequency shift from 10 mhz to 20 mhz, we use two devices to achieve a difference frequency of 10-20Mhz. This frequency is not adjustable. If you need adjustable frequency, we need to re-develop the drivers.

We only have free space AOM for 770nm wavelength. However the fiber coupled 770nm AOM is under development in the year of 2023.

Applications:

Locking 770 nm laser to a potassium cell.

Feature:
Low insertion loss
Compact
Stable performance
Custom Configuration
