Latest Patents

One of his latest patents is titled "Method and arrangement for spectral broadening of laser pulses for non-linear pulse compression." This invention discloses a method and arrangement for spectrally broadening laser pulses, which is crucial for non-linear pulse compression. The approach transitions from spectral broadening in a waveguide to a suitably shaped lens conductor. This arrangement is designed to be non-sensitive to variations in pulse power, position, and parameters of the laser beam. The spectrally broadened pulses can be compressed effectively while maintaining the quality of the laser beam. This is achieved by dividing the non-linear phase required for spectral broadening into smaller steps that can be separated without non-linearity. The invention overcomes limitations related to pulse powers and develops a pulse energy range that is not feasible with traditional glass fibers.

Another significant patent is for an "Optically end-pumped slab amplifier comprising pump modules arranged in a distributed manner." This invention features an optically end-pumped amplifier with a plate-shaped optical gain medium. It includes multiple pump laser units designed to optically pump the gain medium through its narrow side surfaces. The pump laser units create an elongated beam cross-section that propagates freely through the gain medium. The arrangement ensures that the principal axes of the beam bundles impinge on the pumped side surfaces at an angle to one another, allowing for effective superimposition of the beam cross-sections.
