Laser interferometry sits at the heart of modern precision measurement, driving breakthroughs in semiconductor lithography, gravitational wave detection, and ultra-precise nanometrology. As industries demand sub-nanometer resolution and extreme long-term stability, traditional optical setups are hitting their physical limits. To push beyond these boundaries, optical engineers are increasingly turning to heterodyne interferometry. At the core of this transition is a critical component: the Acousto-Optic Frequency Shifter (AOFS).
