Small droplets of supersaturated hen egg white lysozyme (HEWL) solution were exposed to intense linearly polarized laser pulses with different wavelengths, intensities, and pulse durations. Laser irradiation under some conditions significantly increased the number of droplets in which crystals were observed in a given time period, compared with nonirradiated samples. As a general rule, nonphotochemical laser induced nucleation (NPLIN) in lysozyme solutions was more effective with shorter aging time, 532-nm wavelength, higher peak intensity, and shorter pulse duration. Bovine pancreatic trypsin (BPT) was also examined using NPLIN, showing the potential application of NPLIN to other proteins.
