Ultrafast Enhanced Silver Mirrors incorporate silver coating enhanced with dielectric coating contributing to an increased reflectance between 600-1000nm and low GDD. The 600-1000nm reflection bandwidth is ideal for Ti: Sapphire lasers. The substrates are made from UV Fused Silica, an excellent low-inclusion glass material with superior optical properties, mechanical strength, and low thermal expansion. Compared with our Low GDD Femtoline Mirrors, the ultrafast enhanced silver mirrors can accommodate a wider reflective wavelength range but have a higher GDD and minor LIDT.

Shanghai North Optics offers stocked and custom ultrafast-enhanced silver mirrors with low GDD, high flatness, and precision. Ultrafast-Enhanced Silver Mirrors are a cost-effective alternative to guarantee that ultrashort optical pulses sustain their peak power and are free from the effects of widening that are present in conventional metallic or dielectric mirrors.
