Near-Infrared Acousto-Optic Modulator

Power & Speed: Mastering the Near-Infrared Spectrum

The VL-AOM-NIR Series consists of three high-performance sub-series:

1. 780nm General & Broadband Series: Targeting Ti:Sapphire lasers and Rubidium atom cooling, offering center frequencies from 80-300MHz. Select broadband models feature 50-60MHz 3dB bandwidth for flexible frequency shifting control.
2. 780nm Ultra-High Frequency Series: Designed for applications demanding extreme speed, with frequencies covering 800MHz to 1.5GHz. The ultra-short acoustic wavelength enables a microscopic 0.1mm aperture and nanosecond-level rise times, serving as a precision switch in ultrafast optics.
3. 1064nm High Power Series: Engineered for intra-cavity or extra-cavity control of fiber and solid-state lasers (e.g., Nd:YAG). Featuring large clear apertures from 2mm to 4mm and equipped with water cooling or enhanced conduction cooling, ensuring long-term stability under high-power laser irradiation.

Key Applications

• Ultrafast Pulse Picking : Using 780nm/800nm high-frequency AOMs to select single pulses from mode-locked Ti:Sapphire lasers.
• Cold Atom Physics : Precise frequency shifting for laser cooling and trapping of Rubidium (Rb) atoms at 780nm.
• Laser Marking & Cutting : High-power 1064nm modulators control laser intensity and pulse timing in industrial processing.
• LIDAR & Remote Sensing : Generating stable frequency shifts for velocity measurement and range finding.
