OPTOMAN’s Ion Beam Sputtered (IBS) coatings redefine durability in semiconductor laser optics, maintaining stability and reflectance even after billions of pulses at deep-UV wavelengths. Designed for demanding environments from 193 nm to 1070 nm, these optics deliver longer lifetime and consistent performance in advanced semiconductor processing.

Introducing the SuperHero Power IBS Waveplates, engineered for ultrafast lasers with glue-free, zero-order, air-spaced design and <0.1% reflectance, to deliver femtosecond durability and unmatched polarization stability.

OPTOMAN’s IBS-coated optics enable high-speed, reliable laser communication for space and terrestrial networks. Designed for the 1550 nm telecom window, our laser mirrors, beam splitters, and dichroic mirrors ensure minimal absorption, low scattering, and long-term spectral stability. These space-grade components preserve signal strength, maintain polarization, and support mission-critical free-space optical links, overcoming the limitations of RF communication.

This white paper explores advanced optical coatings for 193 nm ArF excimer lasers used in semiconductor lithography and micromachining. It compares fluoride-based and dielectric oxide coatings, highlighting how dielectric oxide coatings offer superior durability, low maintenance, and long-term stability in demanding deep UV (DUV) laser environments.

Surface defects like scratches, digs, or particles are a leading cause of premature laser-induced damage in high-power optical systems. In this whitepaper, OPTOMAN and DIOPTIC present how automated inspection with the ARGOS matrix and raster scan LIDT mapping can detect critical defects down to 1 µm. The findings show that even tiny absorption-inducing defects can reduce LIDT by over 40%. Learn how advanced metrology, defect mapping, and IBS coatings help minimize failure risk in optics for demanding applications like ICF and directed energy systems.

Large-diameter optics are essential components in some of the most advanced and demanding optical systems — from imaging systems in astronomical telescopes and ultrashort pulse compressors to inertial confinement fusion systems, large-scale interferometers, and directed energy laser weapons. This tech note covers the key factors to consider when choosing and using large optics in demanding laser setups.

Silicon carbide (SiC) is favored for laser mirrors in space and defense applications due to its light weight, high thermal conductivity, and mechanical robustness. Learn more about OPTOMAN IBS Coated SiC Mirrors​ in the following tech note.

Building on the success of Non-Degrading UV Optics, OPTOMAN introduces Non-Degrading Mirrors for Ti:Sa lasers and OPCPA laser systems, offering broadband coverage with no color change — ensuring uptime and reducing maintenance costs.

It’s easy to assume that having the highest possible LIDT guarantees the suitability of laser optics for a high-power system. However, the UV part of the spectrum poses significant threats to laser optics, causing fatigue in the coating and leading to degradation and color change. OPTOMAN has a solution – learn more in this tech note.

Low Absorption Protective Windows are widely used in laser processing to ensure high transmission of laser energy, protect laser system, and minimize thermal effects. Find out how OPTOMAN handles it in this tech note.

Absorption in chirped mirrors can cause thermal lensing, which is not ideal and can lead to several problems. This will not happen with OPTOMAN new Chirped mirrors that feature 5 times lower absorption than market standard chirped mirrors. Find out more in this tech note.

The pinnacle of peak powers – TW and PW lasers – enable various applications, including material processing, fusion, and ultrafast processes in physics. But this sometimes comes at the cost of a headache for coating engineers, especially when designing high-power laser mirrors that can withstand extreme intensities. In this tech note, learn how OPTOMAN avoids that and deals with extreme powers.
