ARTICLE OF THE HOUR Diode-Pumped Lasers
Performance, Reliability Enhance Applications
The latest technology advances take diode-pumped solid-state lasers into new realms of power and wavelength, enabling many new applications. Neodymium-doped crystals and glasses such as Nd:YAG (neodymium:yttrium aluminum garnet) have long been used as laser gain materials. Optically pumped, they produce an output wavelength close to 1 µm, and the excited-state lifetime of neodymium allows both CW and pulsed (Q-switched) operation. The output of powerful flashlamps and arc lamps...
