  • Single laser cavity for generating TE or TM modes
    Patent number: 3936770
    Abstract: A dye laser, pumped by a nitrogen laser, has been made to operate in both the TE.sub.01 and TM.sub.01 rotationally symmetric modes, regardless of the variation in laser wavelength. By changing the spacing of lenses within the optical cavity, the single laser can be made to switch from the TE.sub.01 mode to the TM.sub.01 mode and back again to the TE.sub.01 mode.
