Co-doping of Holmium (Ho) and Dysprosium (Dy) with Erbium (Er) for Low-Cost High-Efficiency Diode-Pumped Laser at 3-Micron Meter Wavelength Range
For many applications, the output of a laser diode is coupled into an optical fiber to direct the light beam more easily. This fiber can be doped with rare earth metals such as Erbium to increase efficiency and absorption. Instead of using Erbium (Er3+) exclusively for doped fiber lasers, this method proposes the use of codoped Er3+ fiber lasers with...

High Power Mid-Infrared Supercontinuum Fiber Lasers at 2-5 µm
Researchers at the University of Arizona have developed a supercontinuum laser that has high power output over the 2-5 micron wavelength range. Background: There are various methods for generating a mid-infrared laser source. The problem commonly faced is that it is difficult to emit on a supercontinuum in the IR region. Most competing lasers emit...

Novel Method of Generating Nearly Non-Diffracting Beams
Researchers at the University of Arizona have developed a method to efficiently generate high power Bessel-like beams using methods that are significantly simpler than those commonly used. The new method allows fine tailoring of output beam characteristics and works over a large range of wavelengths or with white light sources. This novel method provides...
