2. General Description
2.1. Intended use
The nanio is a diode-pumped solid-state laser system designed for OEM applications
as part of an integrated laser-based materials processing system. It offers a choice of
output wavelengths and powers with repetition rates up to 500 kHz and excellent
beam quality and stability.
The laser fails safe with no beam output and therefore must not be used where the
beam is part of a safety system; for example, as a light barrier.
2.2. Laser Head
Figure 7 - Laser head
The laser head consists of a diode module and a resonator module. The resonator
module is supplied in several lengths depending on the output specification. All
electrical and cooling connections are on the end face of the diode module. Laser
ouptut is emitted from the end face of the resonator module and can be configured so
that the beam axis is to the left or right of the centre line. The laser head can be
mounted using the bottom surface (preferred) or either side face. In each case, a three-
point fixing is provided with precise and repeatable location assured by means of
precision reference holes and slots for dowel pins.
The complete assembly is sealed to prevent the ingress of dust and humidity and is
fitted with a desiccant cartridge. It is temperature stabilised by means of stainless steel
cooling pipes embedded under the base of the resonator module and into a Peltier
cooler in the diode module.
Important!
Never open the laser head unless. No user serviceable parts inside.
The laser head contains the following key components:
• One or two laser diode modules with collimating optics
• Control electronics
