Neodymium
Doped Yttrium Orthvanadate (Nd:YVO4)
|
Nd:YVO4
is one of the most efficient laser host crystal currently
existing for diode laser-pumped solid-state lasers. Its large
stimulated emission cross-section at lasing wavelength, high
absorption coefficient and wide absorption bandwidth at pump
wavelength, high laser induced damage threshold as well as
good physical, optical and mechanical properties make Nd:YVO4
an excellent crystal for high power, stable and cost-effective
diode pumped solid-state lasers. Recent developments have
shown that Nd:YVO4 can produce powerful and stable IR, green,
bule lasers with the design of Nd:YVO4 and frequency doubling
crystals.

Compared
with Nd:YAG and Nd:YLF for diode laser pumping, Nd:YVO4 lasers
possess the advantages of lower dependency on pump wavelength
and temperature control of a diode laser, wide absorption band,
higher slope efficiency, lower lasing threshold, linearly polarized
emission and single-mode output. For the applications in which
more compact design and the single-longitudinal-mode output
are needed, Nd:YVO4 shows its particular advantages over other
commonly used laser crystals. The diode laser-pumped Nd:YVO4
compact laser and its frequency-doubled green, red or bule laser
will be the ideal laser tools of machining, material processing,
spectroscopy, wafer inspection, light show, medical diagnostics,
laser printing and the most widespread applications. |
