Activated Phosphate Laser Glasses

Description

Activated phosphate laser glasses are a type of laser active material that is commonly used in solid-state lasers. These glasses are made from phosphate-based glass compositions that are doped with rare earth ions, such as neodymium, erbium, or ytterbium, which allow them to amplify light through stimulated emission.

One of the main advantages of activated phosphate laser glasses is their ability to generate laser emissions at a wide range of wavelengths, from the near-infrared to the mid-infrared region. This makes them suitable for a variety of applications, including industrial processing, medical surgery, and remote sensing.

Activated phosphate laser glasses are typically pumped by a flashlamp or a diode laser, which excites the rare earth ions in the glass and causes them to emit light at a longer wavelength. These glasses can also be mode-locked to generate ultra-short pulses in the picosecond or femtosecond range.

Another advantage of activated phosphate laser glasses is their relatively high thermal conductivity, which allows them to dissipate heat efficiently and reduce thermal effects such as thermal lensing. This makes them suitable for high-power and high-repetition rate applications.
