…used, but in most
applications, to obtain a reasonable quality beam, either an
aspheric lens or a lens group is used. Both the aperture and
the focal length of most diode beam collimating aspheric
lenses are several millimeters. Usually the numerical aperture
of the lens is smaller…

…astigmatism is simultaneously corrected, as can be seen in
Fig. 10. The shape of the microlens is also shown in Fig. 10.
The two surfaces are aspheric to reduce the spherical
aberration. Although it is probably impossible to directly
polish such a microlens, the microlens can be made by…

…and correct the beam astigmatism. As
shown in Fig. 9, a laser diode beam is coupled into a piece of
single mode optical fiber with two aspheric lenses. Optical
fiber theory indicates that a piece of single mode fiber much
longer than the laser wavelength can sufficiently "mix" the…
