Title: Vibrationally-Resolved Sum-Frequency Generation With Broad Bandwidth Infrared Pulses
Published: October 15, 1998
Abstract: We present a novel procedure for vibrationally-resolved sum-frequency generation (SFG) in which a broad-bandwidth IR pulse is mixed with a narrow-bandwidth visible pulse. The resultant SFG spectrum is dispersed with a spectrograph and detected in parallel with a scientific grade CCD detector, enabling rapid and high signal to noise data acquisition over a 400 cm-1 spectral region without scanning the IR frequency.
