Provisional entry — research in progress
This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.
The Femtochrome FR 103 autocorrelator is a series of non-linear crystal autocorrelators for measuring the temporal width of ultrashort optical pulses. The FR-103XL variant offers a pulsewidth resolution of less than 1 fs and a wavelength range of 410 nm to 10 µm. The FR-103MN is a compact version with similar resolution and a wavelength range of 410 to 5000 nm.[1]
What it is
Applications
The FR 103 is suited for low power lasers and for pulses from mode locked lasers over a broad wavelength range.[1]
