Titanium–sapphire Laser Technology

Femtosecond solid-state lasers, based on the Ti:sapphire gain medium, have revolutionized the field of ultrafast science in the past decade. Titanium-doped sapphire is a widely used transition-metal-doped gain medium for tunable lasers and femtosecond solid-state lasers. This type of fiber lasers have several advantages such as simplicity, excellent thermal conductivity, and stability. Nevertheless, researchers continue...

Mid-IR and far-infrared (FIR) CO2 Lasers

Infrared is usually divided into 3 spectral regions: near, mid and far-infrared. The boundaries between the near, mid and far-infrared regions are not agreed upon and can vary. The main factor that determines which wavelengths are included in each of these three infrared regions is the type of detector technology used for gathering infrared light....
