. Specifically, the focusing lens used to
achieve a 70 µm diameter via with a CO laser
has twice the focal length of the lens required
to achieve the same via size with a CO

laser.
This longer focal lens provides greater depth
of focus, which…

will develop positive thermal lensing with two adverse
consequences: the mode matching between pump
diode and resonator mode is worsened and the
resonator eventually becomes unstable. A detailed
study of designing NPROs in the thermal lensing
regime [7] shows that when…

…each with 25% efficiency.
A second potential limitation of this architecture is related to the focusing lens L2 in Fig.
1. If the incidence angle of the diffracted beam on lens L2 is too large, then the beam reflected
by the micromirror will clip the aperture resulting in a low…
