  • Pure crystal exciton laser amplifier and method of operation
    Patent number: 4626792
    Abstract: A laser amplifier and method as disclosed wherein excitons in a pure insulator or semiconductor crystal are triggered by incident resonant laser radiation. The excitons are created by an external intermittent radiative source, and stimulated decay produces light output at a wavelength characteristic of the crystal. The radiative source produces light at the same wavelength as the light output produced by stimulated exciton decay, thereby producing an amplified output.
