Nonlinear Optical Devices for Biophysical Studies
Yb:KGW Second Harmonic-Pumped Non-collinear Optical Parametric Amplifier (NOPA) for two-dimensional fluorescence spectroscopy exploring the assembly and functional mechanisms of DNA replication complexes that are central to our understanding of gene expression.
Pumped by the fundamental output (1035nm) from a Yb:KGW laser the NOPA produces ultra-broad bandwidth pulses for spanning the absorption spectra of fluorophores of interest. The NOPA emits pulses at 250KHz, 1uJ/pulse, >90nm (FWHM), and a Gaussian spatial profile.
Ti:Sapphire Second Harmonic-Pumped Non-collinear Optical Parametric Amplifier (NOPA) for two-dimensional fluorescence spectroscopy.
