Title: Valdas Pasiskevicius: Innovator in Coherent Light Sources and Microchip Lasers
Introduction
Valdas Pasiskevicius is a notable inventor based in Lidingo, Sweden. He has made significant contributions to the field of laser technology, particularly in the development of coherent light sources and microchip lasers. With a total of 2 patents to his name, Pasiskevicius continues to push the boundaries of innovation in his field.
Latest Patents
Pasiskevicius's latest patents include a method and device for generating visible coherent radiation through a coherent light source based on sum-frequency mixing. This innovative approach utilizes a first fundamental beam from a diode laser and a second fundamental beam from a diode-pumped solid-state laser. The mixing process is facilitated by a quasi-phasematching element within the resonant cavity of the solid-state laser, with feedback provided to stabilize the diode laser.
Another significant patent is for a Q-switched laser, which features a microchip laser arrangement capable of emitting Q-switched laser pulses at 1.54 µm. The lasing medium is primarily composed of Yb:Er-glass, while the Q-switch utilizes a saturable absorber made from cobalt-doped spinel crystal. This arrangement is designed to form a monolithic body, with dielectric stacks deposited on the surface to create a resonant laser cavity. The active medium is pumped using an InGaAs laser diode that emits light at 0.97 µm, aligning well with the absorption characteristics of the Yb:Er-glass material.
