Invention:
Researchers at the University of Arizona have developed a semiconductor disk laser that is engineered and fabricated to have sub wavelength spaced quantum wells to efficiently use all carriers available for lasing. The technology includes semiconductor saturable absorber mirrors (SESAMs). With the compact spaced quantum wells and absorber mirrors one can achieve mode-locking on the order of femtoseconds (10-15s) over a wide range of wavelength emissions (1200nm-1300nm) that can’t be done with conventional solid-state or semiconductor lasers. The novel lasers can achieve high pulse power and variable wavelengths.
Applications:
- Medical imaging
- Remote sensing
- Telecommunication infrastructure
Status: issued U.S. patents #9,466,948, 9,853,417, and 10,122,150
