High signal-to-interference ratio dual-frequency laser High signal-to-interference ratio dual-frequency laser

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

	633nm	10-100mW	The 633nm laser generated by sum frequency can output two lasers with frequency difference of 2-30MHz which can be adjusted arbitrarily after passing through the dual-channel acousto-optic frequency shifter. One of the channels can be stabilized by iodine molecules to achieve stable dual-wavelength fixed frequency difference output.	Narrow line width Frequency difference adjustable High sideband suppression ratio Never mode-hop
	780nm	10-100mW	The 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.
