High signal-to-interference ratio dual-frequency laser

Based on narrow linewidth laser and dual-channel acousto-optic frequency shifter, frequency accuracy can achieve narrow linewidth dual-frequency laser output. The frequency difference can be adjusted arbitrarily. The laser linewidth is narrow and never mode hopping, so it can be used for optical precision measurement.

 633nm20mWThe 633nm laser generated by sum frequency can output two lasers with a frequency difference of 2-30MHz, which can be adjusted arbitrarily, after passing through a dual-channel acousto-optic frequency shifter. One of the channels can be stabilized by iodine molecules to achieve a stable dual-wavelength fixed frequency difference output.

 780nm20mWThe narrow linewidth 780nm laser outputs two lasers with a frequency difference of 2-30MHz that can be adjusted arbitrarily after passing through a dual-channel acousto-optic frequency shifter. One of the channels can be stabilized by rubidium atoms to achieve a stable dual-wavelength fixed frequency difference output.
