Abstract: An intracavity plasma solid state laser with an emission line radiation source of determined wavelength seeding a semiconductor laser gain medium providing a high power laser beam of the determined wavelength. A plasma cell generates a determined wavelength based on an atomic emission line that is received by the semiconductor laser or laser diode having a broadband output encompassing the determined wavelength received from the plasma cell. The laser diode locks on to the determined wavelength and emits a high powered laser beam of the determined wavelength. The intracavity plasma solid state laser creates a laser beam of narrow linewidth comparable to the natural Voight or Doppler linewidth of atomic transition and higher power in a smaller size than previously possible. The intracavity plasma solid state laser is easily manufactured and suitable for placement in an array for targeting a predetermined area.
