The invention discloses a total reflection type halation-eliminating and light-beam-homogenizing optical
system. The total reflection type halation-eliminating and light-beam-homogenizing optical
system comprises a first
hyperboloid reflecting mirror, a first off-axis parabolic mirror, a first curved-surface reflecting mirror array, a second curved-surface reflecting mirror array, a second off-axis parabolic mirror and a second
hyperboloid reflecting mirror and is characterized in that the
light beam deflection angles of all the mirrors are 90 degrees, and the
central symmetry faces of all the mirrors are located on the same plane. The total reflection type halation-eliminating and light-beam-homogenizing optical
system novel in structural design is based on the combining features of the
hyperboloid reflecting mirrors and the off-axis parabolic mirrors, the
light beam homogenizing and shaping and halation eliminating features of the two reflecting mirror arrays and the direct
water cooling performance and good
thermal conductivity of the
metal mirrors, is applicable to the homogenizing and shaping of optical output type
laser, especially has advantages in the
light beam homogenizing of myriawatt, high-power and large-optical-
fiber-
diameter optical fiber output type
laser devices, can greatly increase the application performance of
laser machining such as laser cladding and
quenching.
