Latest Patents
One of Haas's latest patents is titled "Electro-optic harmonic conversion to switch a laser beam out of a cavity." This invention allows a laser beam to escape a laser cavity by utilizing an externally applied electric field across a harmonic conversion crystal. The amplification occurs within the laser cavity, and the laser beam is switched out by harmonically converting the laser light with dichroic or polarization-sensitive elements. This method alters the optical path of the harmonically converted laser light, and modulation of the laser beam can be achieved by varying the external electric field.
Another significant patent is "Two-dimensional optimization of free electron laser designs." This patent presents off-axis, two-dimensional designs for free electron lasers that ensure the correspondence of a light beam with a 'synchronous electron' at an optimal transverse radius. This design aims to increase beam trapping efficiency and enhance laser beam wavefront control, thereby reducing optical beam diffraction and other negative effects.
