Abstract
An illumination system is disclosed for providing dual excitation wavelength illumination for non-linear optical microscopy and micro-spectroscopy. The illumination system includes a laser system for providing a first train of pulses at a center optical frequency ω, a frequency converting system for providing at least a second train of pulses at a center optical frequency ωand a third train of pulses at a center optical frequency ω, where ωis different from ωand ωresponsive to the first train of pulses, an amplifier system for amplifying the second train of pulses to provide an amplified second train of pulses, and an adjustment means for adjusting a time delay between the amplified second train of pulses and the third train of pulses for the dual-excitation wavelength illumination.
