Neodymium-doped vanadate has become the crystal of choice for many diode-pumped lasers, primarily because the absorption cross section for 808-nm laser-diode pumping to the neodymium upper laser level is nearly eight times greater than the corresponding value in Nd:YAG. Other advantages of vanadates over the traditional YAG host are their higher emission cross sections, which result in lower CW laser thresholds, and their broader pump-light absorption bandwidths. A drawback of yttrium vanadate (Nd:YVO4) is its low thermal conductivity, but gadolinium vanadate (Nd:GdVO4) has thermal...Read full article
