Analog frequency modulated laser using magnetostriction
Patent
·
OSTI ID:6542178
This patent describes an analog frequency modulatable laser. It comprises: an active lasable medium in which stimulated emission of electromagnetic radiation is producable, a first and second radiation reflecting means spaced apart a predetermined distance and operatively connected with the active medium defining an optical axis therebetween for causing generated stimulated emission radiation to traverse the medium by multiple reflections between the reflecting means in directions substantially parallel to the optical axis and forming a resonant cavity at a resonant frequency of radiation within the stimulated emission radiation spectrum of the active medium, a portion of the reflected radiation being extracted from the active medium, and magnetostrictive responsive means disposed about and bonded to portion of the outer periphery of the medium for changing the optical path length between the first and second radiation reflecting means, for changing the resonance of the cavity, and for changing of the frequency of the reflected radiation in response to a magnetic field applied to the magnetostrictive responsive means.
