(2) Branch Unit
Cover
Do not remove this cover except when installing and removing the
optical fiber.
(3) Guide Beam
Reflecting
Mirror
Adjusts the guide beam (visible laser beam) so that this beam passes
down the center of the YAG laser beam’s optical path.
(4) Power Monitor
Unit
Detects the YAG laser beam and measures its power.
(5) Resonator
Mirror Holder
Holds the resonator mirror. Light excited in the Laser Chamber is
amplified between the two resonator mirrors and output as a laser beam.
(6) Resonator
Shutter
This shutter is used to intercept laser light. When this shutter is closed,
no laser light is output even if the flashlamp comes on.
(7) Guide Light
Oscillator
This oscillator outputs guide light (red visible laser).
Because YAG laser for welding is invisible, red guide light is used
to perform oscillation adjustment, incident adjustment, welding point
positioning, etc.
(8) Laser Chamber Contains the flashlamp and the YAG rod. The flashlamp lights up to
excite the YAG rod and emit laser beam.
(9) Timesharing
Unit
(Only for
timesharing
version)
Mirror to reflect the laser light. This optical-path-switching mirror directs
the laser light to the selected optical fiber.
(10) Beamsplitter
(Up to 4 optional
deliveries)
Splits a laser beam into the number of deliveries and reflects them
onto each laser beam input unit. Depending on the specification, 1 to 4
beamsplitters are installed.
(11) Branch Shutter
(Up to 4 optional
deliveries)
When closed, the laser light is blocked not to output. Depending on the
specification, 1 to 4 branch shutters are installed.
(12) Laser Beam
Input Unit
(Up to 4 optional
deliveries)
Connect the optical fiber to this unit. The Laser Beam Input Unit projects
a laser beam from the laser chamber into the optical fiber. Depending on
the specification, 1 to 4 laser beam input units are installed.
