COVER STORY

High-Power Fiber Lasers

Jeff Hecht

Fiber lasers have laid down a strong track record for high-power, high-quality beams for industry and even the military. The challenge is pushing them beyond their current limits.

IMAGE OF THE WEEK

Multiphoton microscopy image
Multiphoton microscopy image

Multiphoton-microscopy image of ex vivo human dermal skin tissue. Second-harmonic generation (red) images collagen fibers; third-harmonic generation (green) shows the fiber interfaces; and two-photon excited autofluorescence (blue) captures the elastin fibers. Images aquisition was done with a custom LabView Script; image processing was done using ImageJ. Colors were arbitrarily assigned to the grayscale images.
