Diamond Raman Lasers
Scientists are using high-purity synthetic diamonds to create novel devices that offer increased laser power, brightness and wavelength reach.
The “engine room” of a diamond Raman laser: rectangular slabs of high-purity synthetic diamond up to 1 cm long.
Gallium arsenide, YAG, sapphire and glass fibers are all prominent examples of materials that have made revolutionary changes to laser technology. Their robustness and exceptional optical properties are two of the many reasons for their success. But recent advances in synthesis of diamonds—a “new” material with better physical and optical properties (sometimes by orders of magnitude)—may enable massive increases in optical device capability.
