ABSTRACT:
A laser apparatus includes an optical resonator having a laser medium and generating a laser light. A wavelength selection element selects a given wavelength of the laser light. The selected wavelength resides within a gain bandwidth of the laser medium. A sealed container houses the wavelength selection element. The sealed container may be filled with a gas. A density of the gas within the sealed container may be changed to vary the selected wavelength.
