Analysis of Core Principles and Applications of Laser Lens System (Part 3)
Izingxenye Ezisemqoka Zobuchwepheshe Nezinselelo
- High Precision Requirement: The processing precision of optical mirrors is usually at the nanoscale; any defect will affect the spot quality and system performance.
- Thermal Management: Especially in high-power laser applications, a large amount of heat is generated. Excellent heat dissipation design (such as using materials with low thermal expansion coefficients like fused silica) is required to prevent thermal deformation of the lens.
- Laser-Induced Damage Threshold (LIDT): Izi zifakelo nezinto ezikwi lens kufuneka zikwazi ukumelana nokukhanya kweelaser ezinamandla aphezulu ngaphandle kokulimala.
- Special Coatings: It is necessary to design anti-reflection coatings (to reduce reflection loss) and high-reflection coatings for specific laser wavelengths.
- Cost: Particularly for lenses involving complex optical components such as Diffractive Optical Elements (DOE) and aspherical mirrors, the design and manufacturing costs are very high.
