Durable Optical Dove Prism In High-power Laser Systems
Material
1.High-grade optical glass (e.g., N-BK7, fused silica) for thermal stability and low absorption.
2.Robust coatings: Anti-reflective (AR) or dielectric coatings to enhance durability and minimize energy loss in high-power laser environments.
Properties
1.Thermal resistance: Withstands high-power laser beams without deformation.
2.Precision-polished surfaces: λ/10 surface flatness for minimal wavefront distortion.
3.Low coefficient of thermal expansion (CTE): Ensures dimensional stability under thermal stress.
4.High laser-induced damage threshold (LIDT): Resists degradation from intense laser exposure.
Function
1.Image rotation: Rotates images by 180° without altering parity, critical for beam steering and alignment.
2.Beam displacement: Maintains beam path direction while offsetting spatial position.
3.Polarization preservation: Minimizes birefringence effects for coherent laser systems.
Applications
1.Laser machining: Beam delivery in industrial cutting/welding systems.
2.Medical lasers: Endoscopic imaging and surgical laser alignment.
3.Defense & aerospace: Target designation and LIDAR systems.
4.Scientific research: Interferometry and spectroscopy setups.
