Acousto-optic modulator, polarizer, optical frequency shifter (AOM, AOD)

Intensity modulation of various lasers from UV to IR is possible. It maintains high diffraction efficiency and excellent temperature stability.

Acousto-optic (AO) intensity modulators (AOM), deflectors (AOD), and optical frequency shifters utilizing various crystals have good diffraction efficiency and can be widely used for both scientific and industrial purposes. In addition to single-channel drivers for AOMs, there are also two-channel AOM drivers and OEM models available. There are also XY two-axis deflectors (DTD) and Q-switches.

Frequency Shifter FS1S

Frequency Shifter FS1S

A frequency shifter optimal for heterodyne measurements that slightly shifts the frequencies of two lights and stabilizes the difference between the two frequencies. 【Configuration】 It consists of two AOMs (acousto-optic modulators) and their drivers. The incident light with a light frequency (f0; for HeNe laser, 474THz) is split into two paths, and each light frequency is shifted to f0+f1 (approximately 80MHz) and f0+f2. The shift amount is very small (f1/f0 ~ 0.0000002), but this slight shift enables processing by electronic circuits, realizing optical heterodyne measurements. The frequency stability of the frequency shifter is achieved by synchronizing the oscillation frequencies of the two drivers that supply high-frequency power to the two AOMs. This provides a level of frequency stability that cannot be achieved with independent drivers. ● For other functions and details, please download the catalog.
