General Description
Acousto-Optic Modulators (AOM) are state-of-the-art devices engineered to modify the intensity of incident laser beams through amplitude modulation. Operating outside the laser cavity, these modulators utilize RF drivers to facilitate both digital (on/off) and analog modulation modes, such as sine, square wave, or linear modulation, to suit a variety of operational needs. The performance of an AOM is characterized by its rise/fall time, determining the achievable modulation speed and bandwidth. To ensure optimal speed, POC AOMs are designed to control the beam diameter precisely, minimizing the rise/fall time to as low as 6 ns. With a frequency range of up to 300 MHz, POC’s AOMs cater to applications requiring fast, reliable modulation. Using high-quality materials such as Crystalline Quartz (CQ) and Tellurium Oxide (TeO2), the devices ensure low insertion loss and high extinction ratios, making them ideal for a wide range of industries, from medical technology to material processing.General Applications and Examples
- Laser Marking AOMs provide precise modulation control for high-speed marking of materials. This ensures clean, accurate marks, making the technology suitable for industrial and consumer product marking.
- Photolithography In semiconductor manufacturing, POC AOMs enable fine control of laser intensity for lithographic patterning, contributing to the precision fabrication of micro-scale electronic components.
- Material Processing High-frequency modulation allows POC AOMs to perform advanced processes like laser cutting, welding, and micromachining with exceptional precision.
- Medical Applications AOMs are utilized in laser-based medical devices for procedures such as precise tissue ablation and therapeutic treatments requiring controlled laser intensity.
