Abstract
A method is provided to control the lasing wavelength of a laser material without changing or adjusting the mechanical components of a laser device. The rate at which the laser material is pumped with the pumping energy is controlled so that lasing occurs at one or more lasing wavelengths based on the rate. The lasing wavelengths are determined by transition lifetimes and/or energy transfer rates.
