Non-degrading ultrafast optics
Building on the success of Non-Degrading UV Mirrors, OPTOMAN has expanded this technology to serve a broader range of ultrafast laser applications. Our non-degrading ultrafast optics are now more reliable and durable than ever before, ensuring consistent optical performance, better coating thermal conductivity, and significantly extending the operational lifetime of ultrafast laser systems. These mirrors maintain reflectivity and spectral characteristics even after exposure to over 3.6 × 10¹² pulses at 100 kHz.
By combining Ion Beam Sputtering (IBS) technology with application-specific coating designs, OPTOMAN’s Ultrafast Optics:
- Estimated to withstand over 3.6 × 10¹² pulses at 100 kHz
- Show no color change after long-term use
- Maintain stable spectral performance and reflectivity
- Withstand LIDT > 0.7 J/cm² @ 1030 nm, 200 fs
- Lowers your system’s total cost of ownership
Non-degrading ultrafast optics are ideal for laser systems operating in demanding environments across various industries. High-power Ti:Sapphire and OPCPA systems used in ultrafast spectroscopy, attosecond science, and high-field physics require stable, long-lifetime optics. Also, femtosecond lasers used in precision processing, micromachining, stent patterning, and LIDAR systems benefit from components that maintain consistent performance without frequent replacement.
LIDT and endurance measurements were performed at Lidaris to prove the “non-degrading” statement.
According to the measurements, OPTOMAN Non-Degrading Ultrafast mirrors can withstand 0.7 J/cm² laser fluence with no color change after prolonged exposure to ultrafast laser irradiation.
