AR Coated Laser Optics
Overview
As OPTOMAN is playing a protagonist role for laser system developers, the beam delivery setup in machines designed for micro drilling, micro structuring, micro shaping, and laser processing in general, motivated OPTOMAN to optimize Ion Beam Sputtering coatings for laser processing applications.
Key Problems
OPTOMAN has fought many battles. From the experience gathered throughout these years, he highlighted main problems laser processing faces.
Thermal Lensing effect.
Short duty cycle and lifetime of machines caused by coating absorption and laser damage.
Beam profile deformation.
Polarization sensitivity requires beam delivery components to be optimized for s and p at the same time.
Multiple wavelengths coverage in the system.
What can OPTOMAN do for the laser processing market?
Lower cost of ownership due to enhanced lifetime.
OPTOMAN’s concentration on high LIDT and enhanced lifetime IBS coatings allows industrial players to forget about headaches when components have to be replaced after a short period of time. Learn more about this here.
Laser optics made by OPTOMAN, due to low absorption, low surface roughness and high batch-to-batch repeatability, offer higher longevity than optics produced by others, thus lowering the Total Cost of Ownership and ensuring the cost of supply wouldn’t be just the tip of the iceberg when purchasing optics.
AR Coated Laser Optics for Laser Processing
Lenses from OPTOMAN are IBS coated and optimized for high laser power applications. This means that they can be used for intracavity, multi-kW CW, and ultrafast pulse applications.
For the sake of performance, we choose optimized and low absorption fused silica so that they are free of thermal shift during operation. Coatings being near bulk, durable and non-porous provide negligible fatigue and insensitive environmental performance and are perfect for Laser Processing applications.
