Additional information / notes: | Based on a supercontinuum generated in photonic crystal fiber pumped by a Nd micro-chip laser. The continuum is then dispersed in a multi-mode fiber. Applied to rapid LIF excitation scans. The scanning width stated below was limited by the photodetector and could be extended by at least 2000 wavenumbers. |
