Diode-pumped passively
Q-switched solid-state
laser is widely used for
remote sensing, distance
measurement, laser medicine,
laser micromachining,
optics data storage etc.
fields with its
advantages of narrow
pulse width, high peak
power, high repetition
frequency, high
conversion efficiency,
compact size.
This is the typical
experiment of research
on pulsed laser. In the
experiment, there is
1064nm pulsed laser
output by putting Cr:YAG
into the laser cavity
with LD pumped Nd:YAG
Measure the wave shape,
frequency and pulse
width with oscilloscope,
then observe the change
rules of parameters of
wave shape, frequency,
pulse width by changing
the length of cavity and
output mirror with
different transmissivity.
The students can grasp
the adjustment method
with Cr: YAG and the
measurement of pulsed
laser parameters,
finally coming to
conclusion of influence
factors and change
rules. |
