ASOPS Engine

Features Downloads

The ASOPS engine consists of two femtosecond lasers, TL-1000 ASOPS for offset frequency stabilization, an optical trigger unit, a high-speed balanced optical photoreceiver, a personal computer housing the data acquisition card and the HASSP-Scope software for measurement and analysis of time-domain data. The femtosecond lasers can be chosen from either the 1 GHz or the 84 MHz range of lasers
