Recently, CNI researched and
developed the new technology of 491 nm all-solid-state
laser, this R & D success is expected to replace the
argon ion laser in the future.
The unique technique reflects the CNI’
R&D ability in the field of all-solid-state laser. This
is the first time that this wave band laser is obtained
in China, which has filled the gap in this technology.
Currently, the scientific researchers are carrying on
the optimization to this laser, increasing the output
power and optical-optical conversion efficiency.
491 nm laser is the ideal substitute
for the argon ion laser. For instance, in the
application of biology analytic instrument and laser
making lithograph plates printing. Furthermore, 246nm UV
laser will be developed successfully which is based on
frequency doubling of 491 nm cyan laser.
