BEAM PROPAGATION CHARACTERISTICS OF
DIAMOND GEM-SERIES AND K-SERIES LASERS
GEM, G, and
K-Series Beam
Propagation
The following charts describe the beam propagation characteristics
for the GEM-series, G-series, and K-series laser. In the following
tables, the distance is referenced from the front end plate of the laser
head. The tables show only beam diameters up to 1.0 inch (25 mm)
clear aperture optics. Beam diameters that are larger are unsuitable
for most applications. It is recommended that beam expansion be
used for beams propagating over extended distances..
