Laser Cavity Mirror
Laser Cavity Mirrors are precision optical components designed for high-performance laser resonator systems, providing controlled reflection, beam feedback and cavity stability for laser generation and amplification applications. Manufactured from fused silica, BK7 optical glass, sapphire and low expansion glass substrates with high-reflectivity (HR) and partial-reflectivity (PR) dielectric coating structures, these mirrors provide low optical loss, high laser damage resistance and stable reflectivity performance. Chenyu Optics manufactures laser cavity mirrors with HR dielectric, PR dielectric and laser line coating options for solid-state, fiber and gas laser systems.
Laser Cavity Mirror Overview
Laser Cavity Mirrors are precision optical components designed for high-performance laser resonator systems, providing controlled reflection, beam feedback and cavity stability for laser generation and amplification applications.
By using high-reflectivity (HR) and partial-reflectivity (PR) dielectric coating structures on precision optical substrates, laser cavity mirrors provide low optical loss, high laser damage resistance, excellent surface quality and stable reflectivity performance. They are widely used in solid-state lasers, fiber lasers, gas lasers, laser resonators and scientific optical instruments where precise cavity control is required.
Chenyu Optics supports custom laser cavity mirror manufacturing according to customer drawings, including custom reflectivity, wavelength range, substrate and dimension design for prototype and repeat production.
