  • High power tunable infrared mirrorless laser
    Patent number: 4905247
    Abstract: The invention comprises a mirrorless iodine laser having an elongated sealed iodine cell for both receiving and emitting laser energy. A pumping laser is used for projecting a laser beam into the sealed cell along its long axis in order to excite the iodine molecules within the cell and cause their release of laser energy. A heater is used for heating the sealed cell to a temperature that increases the amplified spontaneous emissions (ASE) of the iodine in the sealed cell when it is excited by the pumping laser.
