Abstract
Recently, we demonstrated the use of mirror-only dispersion compensation schemes for non-collinear optical parametric amplifiers (OPAs,1), covering a spectral bandwidth of about 200 THz.2 To support this enormous bandwidth, we used double-chirped mirrors (DCMs, 3), which provide dispersion compensation and high reflectivity from 510 nm to 720 nm. Pulses with less than 6 fs duration are easily reproducible on a day-to-day basis without any compressor adjustment. The DCM compressor therefore considerably simplifies the use of the OPA for spectroscopy experiments with extreme time resolution.
