Femtopower™ CEP, Ultrafast Multipass Ti:sapphire Amplifier with CEP Stabilization


▶Femtopower™ CEP 시스템은 CEP 안정화기능을 제공하는 멀티패스 Ti:sapphire 증폭기입니다. 

▷CEP (carrier envelope phase) 안정화된 sub 30fs 펄스를 제공합니다. (CEP stability < 250 mrad rms)
▷옵션인 PRO 버전은 sub 20fs 펄스를 제공합니다. 
▷최고의 pulse-to-ASE contrast 비를 제공합니다. (pre-pulse <10(-9))
