FAQ
How can IBS-coated dispersive mirrors benefit my Business?
IBS-coated dispersive mirrors are crucial for managing dispersion in ultrafast laser systems. By varying the thickness of dielectric coating layers, chromatic dispersion can be induced through wavelength-dependent penetration depth. Dispersive mirrors come in two main types: GTI mirrors, which provide high dispersion over narrow bandwidths, and chirped mirrors, which offer broader spectral coverage with lower GDD, ideal for compensating bulk materials.
However, high absorption in chirped mirrors leads to heating, creating a refractive index gradient that results in thermal lensing—a distortion of the laser beam caused by uneven heating. Low-absorption chirped mirrors from OPTOMAN specifically address thermal lensing, a distortion caused by heating in high-power laser systems. Through extensive R&D, we’ve reduced the absorption by 5 times, minimizing heat generation and ensuring no unwanted beam distortions and drifts occur. In addition to their optical advantages, OPTOMAN IBS-coated dispersive mirrors offer high Laser-Induced Damage Thresholds (LIDT), making them reliable under ultrafast high-power laser conditions. This durability results in fewer replacements, reduced maintenance costs, minimal downtime and lower total cost of ownership.
At OPTOMAN, our expert coating engineers ensure that each dispersive mirror is finely tuned for your specific needs, providing controlled and precise GDD values and long-lasting solutions for the most demanding laser systems.
How can I be sure that these mirrors will fit my Business needs?
OPTOMAN digs deep into each application, providing highly customized and application-optimized solutions that will fit your business needs.
Together, we will be able to set the priorities that are most important for your application and needs, whether it is reaching fundamental limitations, proving the concept, or making a well-balanced industrial high runner. We keep an open discussion about the main price drivers and help customers optimize BOM costs while maintaining the highest quality level.
Is it possible to test the optics and how scalable is the production?
Yes. Based on the customer’s presented business case, OPTOMAN, with its R&D-driven attitude and collaborative approach, can design, develop, and manufacture products for testing purposes and present a plan for serial production. Different-size IBS coating chambers are very handy in this case because small-scale production can be easily transferred to our giant IBS machine – Albert (the atom smasher), where we can coat large optics or 400-500 units of 1“ laser optics in a single coating run, ensuring high uniformity, meaning that all mirrors will work the same making your laser systems highly repeatable and reliable too.
Moreover, our in-stock optics marketplace, OPTOSHOP, features over 400 different laser optics made with love by OPTOMAN. These optics can be provided for testing directly from stock and delivered in 1-3 business days. After successful tests, OPTOMAN can present the most optimal production plan matching your business needs.
Does OPTOMAN provide optics or only coating service?
Both. 80% of total OPTOMAN revenue comes from complete products, while 20% is generated by providing coating services on customer-supplied substrates. OPTOMAN responsibly oversees the supplier network for reliable substrates and, if needed, can offer a completely European supply chain.
Does OPTOMAN have available substrates ready to coat?
Yes. OPTOMAN has a number of flat substrates, plano-concave and plano-convex lenses, and spherical mirror substrates in stock, ready to be coated. Choosing the in-stock substrate option allows, on average, saving 6 weeks of lead time and reducing end-product cost 3 times.
