High power laser damage & annealing - Justification for ISO Standard Recommendations

This article is brought to you by: 

Values for Laser Induced Damage Thresholds (LIDTs) can vary. Inflated values give a rosy glow to the coater and a redder glow to the end user when their optics damage under seemingly safe conditions. There is much finger pointing within the damage community and there are numerous sources of variance. This situation highlights the importance of following the ISO standards for laser damage testing. 

Hybrid Mode Optical Monitoring – Benefiting from Monochromatic and Broadband Algorithms in the same Coating Process

This article is brought to you by: 

 Broadband monitoring with high signal quality enables use of both broadband and monochromatic layer termination algorithms in the same process when depositing optical interference coatings. Case studies using a bandpass filter and an absorbing layer show how such a “hybrid” approach can lead to the most accurate layer termination.
