Laser devices include all components required for generating
laser light.
Laser device components include:
■ Laser with pump source
■ Energy supply for the pump source, e.g. diode power supply,
lamp power supply
■ Control
■ Cooling unit
Depending on the type and maximum power of the laser device,
it may have other components, such as:
■ Additional components in the mains distribution
■ Cabinet cooler
■ Air cleaner or recirculating air dryer system
■ Gas purging unit
The pump light cable is a flexible connection element between
supply unit and laser head. The pump light is guided in a
light
guide from the pump diode to the laser head. Around the light
guide there are different devices to avoid uncontrolled exit of
laser light and to protect the light guide.
The laser light cable is a flexible connecting element between
laser device and focusing optics. The laser light is guided from
the laser to the focusing optics in a
light guide . For ultrashort
pulse lasers, only so-called hollow-core fibers are suitable due
to the high peak power, where the intensive laser pulse is not
conducted in glass, but in a vacuum, air or another filling gas.
The light guide is surrounded by several devices that prevent an
uncontrolled escape of laser light and protect the light guide.
Focusing optics are optical assemblies. Their main function is to
form the laser beam so that it achieves its maximum power den-
sity at a defined point, the
focal point .
In the reflective focusing optics (RFO), the conical laser beam
coming out of the laser light cable hits the focusing mirror,
which guides the laser beam through the exit port and merges it
in the focal point.
The programmable focusing optics (PFO) includes one or two
scanner mirrors which allow the laser beam to be guided over a
processing field. It is thus possible to produce, for example,
welding seams without moving the focusing optics and the work-
piece.
The distance of the focal point from a certain edge or surface of
the focusing optics is called
working distance . The working dis-
tance of the focusing optics determines the distance in which
the workpieces must be positioned so that they can be proc-
essed with the laser.
