UV & Visible Acousto-Optic Modulator

Spectral Precision: From UV Trapping to Visible Interferometry

The VL-AOM-VIS Series comprises three core sub-categories:

1. 397nm Broadband Series: Designed for 397nm±10nm UV lasers, offering center frequencies of 130MHz, 200MHz, and 300MHz with up to 60MHz 3dB bandwidth, ideal for cold atom experiments requiring rapid frequency tuning.
2. Visible Broadband Series: Targeting 532nm and 633nm lasers with modulation frequencies from 80-200MHz, widely used in laser displays and optical tweezers.
3. Low Frequency Shift Series: 20MHz/40MHz models designed for 633nm, utilizing acousto-optic interaction to generate minute frequency shifts, essential for heterodyne interferometry.

Key Applications

• Quantum Optics & Cold Atom Physics :The 397nm UV modulators are critical for cooling and trapping ions (e.g., Ca+, Yb+) in quantum computing and atomic clock research.
• Heterodyne Interferometry :Low-frequency shift models (20MHz/40MHz) introduce a stable reference frequency shift, enabling high-precision phase measurement in interferometers.
• Laser Doppler Velocimetry :Used to split laser beams and introduce frequency shifts to measure the velocity of fluids or moving surfaces with high accuracy.
• Laser Microscopy & Tweezers :Fast intensity modulation and beam deflection allow for precise control of trapping potentials and scanning in biological imaging.
