The NIF team completed a record 28 laser shots on targets last month, along with two shots without targets. January also saw a significant increase in NIF's experimental flexibility, as the team completed 40 laser wavelength changes – more than double the number in any previous month. Changing the laser wavelength by a few angstroms in different cones of laser beams enables researchers to adjust the amount of energy reaching different areas of the hohlraum targets.
