A heat capacity laser having a solid lasing medium, at least one pumping source that is able to emit a pumping radiation, and an optical cavity that can be characterized by having: at least one device able to homogenize the pumping radiation, a doped lasing medium having a body with a first and a second end and being stretched in the length by more than 6 cm and whose height in cross section is less than its stretching in the length of the lasing medium. The doping concentration in the lasing medium may vary axially. Also either the cavity can have beam forming optics and the doping concentration of the lasing medium is radially uniform, or the cavity can have no beam forming optics and the lasing medium has a doping concentration that may vary radially.
