The Chameleon Vision-S ultrafast laser from Coherent Inc. is used for multiphoton imaging and combines 80-fs pulse widths with high average power and a long wavelength tuning range. It delivers >410 kW of usable peak power, after group velocity dispersion (GVD) precompensation, and hands-free tuning from 690 to 1050 nm. The blend of short pulse widths and high average power translates into high precompensated peak power from a one-box laser. The laser is suitable for multiphoton excitation imaging for several reasons. Its high peak power delivers maximum imaging brightness in deeper tissues and, because it is a true one-box laser with the laser oscillator and GVD precompensator integrated on a single baseplate, it provides good beam pointing stability of 80 μrad per 100 nm of tuning.
