1. Ultrashort pulses write sharp, tiny features and perform microsurgery: sharply focused femtosecond pulses create strong nonlinear effects inside solids that can alter the properties of materials on subwavelength scales, writing waveguides and gratings, and creating voids. They also are used in biomedicine

Abstract

Ultrafast lasers deliver pulses lasting only picoseconds or femtoseconds, squeezing their entire pulse energy into a very thin slice of time. Initially, ultrashort pulses were used mostly in sensing and [...]

Abstract

Subsurface damage such as cracks, voids, and contaminant particles are a fact of life in even the highest quality optics. The damage can be inherent to the type or quality [...]

4. Long-range VCSELs take aim at putting zap into structured cabling: vertical-cavity surface-emitting lasers in the 1310-nm range could lower attenuation and achieve greater distances for singlemode fiber transmission--if reliability, affordability, and marketability hurdles can be overcome

Abstract

Vertical-cavity surface-emitting lasers (VCSELs) are the laser-based light source used in fiber. While VCSELs are currently available for 850-nm transmission only, and are used exclusively with multimode fiber at 1 [...]

6. Analysis establishes 36 kW upper limit on diffraction-limited fiber-laser output

Subjects
Lasers -- Analysis, Laser, Business, Electronics and electrical industries
Abstract

Existing material and other constraints preclude the creation of diffraction-limited continuous-wave fiber lasers or amplifiers with an output of greater than about 36 kW, according to a theoretical analysis done [...]
