Low GDD Ultrafast Broadband Mirrors
Overview
Features
Absolute reflectance Rs>99.8% and Rp>99.8%
Despite broadband design, low GDD ulftrafast mirrors maintain a high reflectivity greater than 99.9%.
Compensated for Group Delay Dispersion (GDD)
Coatings are designed in a way that the GDD is slightly negative. This prevents pulse broadening and helps to maintain high peak power.
Wide spectral bandwidth
OPTOMAN designs mirrors to steer beams with over 99.8% reflection across the wide wavelength ranges, such as from 650 nm to 1200 nm.
Wide cone of AOI
Should you need mirrors operating at a wide range of angles, OPTOMAN is ready to design broadband mirrors with a wide cone of AOI.
- Mirrors with predefined negative or positive GDD.
- Diameter from 3 mm up to 150 mm.
- Spectral range from 200 nm up to 5000 nm.
- Available in multiwavelength or broadband configuration.
- Coatings on substrates with positive or negative curvature.
Optics for Ti:Sapphire Lasers
Ti: Sapphire lasers, featuring relatively broad emission wavelengths, typically between 700 nm and 900 nm, sometimes even 650 – 1100 nm, are the tough challenge for optical coatings manufacturers. Especially when you combine such a broad spectrum together with high power few tens of femtoseconds pulses.
However, optical components shouldn’t cause a headache for laser manufacturers. So if you’re still looking for durable, long-lasting, high LIDT optics for your Ti:Sapphire laser, congratulations – you’re at the right place!
