Photonic Nd-YAG Laser and DL-14 Dye Laser
The Nd-YAG laser is a medium energy laser capable of generating intense
coherent light energy at a rate of 20 pulses/second, with each pulse
lasting for less than 10 nanoseconds. The laser output wavelength
is in the infrared at 1064 nm, but by use of doubler and tripler crystals,
laser output can also be obtained in the green region of the spectrum
at 532 nm, and in the blue at 355 nm. The Nd-YAG laser is designed
to pump the Laser Photonic DL-14 Dye Laser which is capable of producing
coherent, pulsed lasing light over a wide range of wavelengths, dependent
on the laser dye selected.
The combined Nd-YAG/Dye Laser is used as a source for the Laser Spectrofluorimeter
also described in this section, but the individual laser wavelengths
can be used in separate experiments by appropriate placement of mirrors
and fiber optics on the optical table in order to divert the beam.

lasers, please contact Dr. Edward
Birnbaum.
 Laser
Spectrofluorimeter
The laser spectrofluorimeter is a specialized fluorescence instrument
designed to detect the fluorescence of lanthanide ions, especially
europium and terbium, at low concentrations. This instrument uses
a Nd-YAG/dye laser combination as a light source to excite these
ions, causing them to fluoresce. The pattern of fluorescence observed
can be used to study a wide variety of chemical systems, including
calcium-binding proteins, zeolite petroleum cracking catalysts and
high temperature superconductors. If you would like more information
about the capabilities of this instrument, please contact Dr.
Edward Birnbaum.
