Nd Doped Phosphate Glass Nd:Glass

Products Description:

Nd Doped Phosphate Glass is a kind of Laser Crystal with good properties, Neodymium (chemical symbol: Nd) is a chemical element belonging to the group of rare earth metals. In laser technology, Nd Glass Doped Phosphate as a laser crystal have been widely used in high average power laser solid state lasers,laser material processing, range finder and other industrial and scientific applications. The usual pump wavelength is 808 nm (for Nd:YAG; wavelengths for other host materials can somewhat differ), but a higher slope efficiency can be achieved by directly pumping into the upper laser level 4F3/2 with 869-nm light.

The strongest laser transition is that from 4F3/2 to 4I11/2 for 1064 nm, but other transitions are available with longer or shorter wavelengths. In order to achieve lasing on those, lasing at the 1064-nm line needs to be suppressed by inserting an appropriate wavelength filter (usually consisting of one or more dichroic mirrors) into the cavity. Via multi-phonon emission, the populations in levels 4I11/2 to 4I15/2 are quickly transferred to the ground-state manifold 4I9/2. (The lower-state lifetime is much smaller than the upper-state lifetime.) Hence, there is normally negligible population in all these levels, so that neodymium-doped gain media exhibit pure four-level behavior. The exception is the case where the lower level is the ground-state manifold 4I9/2: 946-nm Nd:YAG lasers (and other Nd-based lasers emitting between 900 and 1000 nm) are quasi-three-level lasers, exhibiting a fairly high threshold pump power.
