Introduction |
| |
|
Analysis of its
fluorescence spectrum
has significance
to study the
characteristics and
application of material.
This is a research on
fluorescence and laser
spectrum of He-Ne laser.
Besides, fluorescence
spectrum of Nd:YVO4 and
Nd:YAG are measured and
analyzed. The students
can grasp the concepts
of fluorescence spectrum
and the method of
measurement. The
students can study the
concept of fluorescence
spectrum and the
measurement method, and
then the learning
process of laser
generation,
understanding the
important significance
to improve the pump
light source and the
conversion efficiency of
laser material by the
experiment. |
