Selective Transverse Modes in a Diode End- Pumped Nd:Yag Pulsed Laser
The output beam quality of multi transverse modes of
laser, are relatively poor. In order to obtain better beam quality, one
may use an aperture inside the laser resonator. In this case, various
transverse modes can be selected. We have selected various
transverse modes both by simulation and doing experiment. By
inserting a circular aperture inside the diode end-pumped Nd:YAG
pulsed laser resonator, we have obtained 00 TEM , 01 TEM
, 20 TEM and have studied which parameters, can change the mode
shape. Then, we have determined the beam quality factor of TEM00
gaussian mode.
