Once the Ultra-short laser pulses is generated, it is necessary to keep the pulsed beem profile unchaged in light propagation, the Low Group Delay Dispersion (GDD) mirrors are necessarily used for this purposed. The mirrors of silver coating enhanced with dielectric coating has an increased reflectivity between 600-1000nm and low group delay dispersion (GDD). Then Ultrafast-Enhanced sliver mirrors are ideal for Ti:Sapphire lasers.
Hangzhou Shalom EO offers the stocked and custom ultrafast-enhanced silver mirrors with low GDD, with high flatness and surface quality and substrates made from Corning UV fused silica glass.
