Comprehensive Experiment on Diode
Pumped Solid State Laser |
| |
|
◆ Knowledge
Introduction |
| |
Diode pumped solid state
laser (DPSSL) possesses
high efficiency, small
volume and long life
time. It has potential
in optical
communication, laser medicine,
laser processing and so
on. It is the future
development direction of
solid-state lasers.
The fluorescence lifetime of laser material has
influence on laser.
Through the study of
this experiment,
students can master the
measurement method and
principle of the
fluorescence lifetime of
the solid-state laser
material, and then learn
the role of the
fluorescence lifetime of
the laser working
material in the process
of laser generation. |
