Kerr-Lens Mode-locked Cr:ZnS Laser
(Chapter, 2012)The first Kerr-Lens mode-locked Cr:ZnS laser generates the shortest and highest-energy mid-IR near transform-limited pulses of 69 fs duration at 550 mW output power. The 3.7 nJ pulses have 193 nm wide spectrum around 2.39 µm -
Learning to learn, bolt-on, or integrated? Analysis of student feedback from a pilot with learning to learn integrated into first-year engineering mathematics
(Chapter, 2022)Learning to learn is one of the generic skills that are important to becoming an engineer. One outcome of the education is to be prepared for a role as an engineer with lifelong learning. In this paper, I convey experiences ... -
