The solid-laser combined concentrating cavity 1064nm YAG for laser welding machine
Introduction:
The function of the gold-plated concentrating cavity is to
effectively couple the pump source with the working substance,
thereby affecting the uniformity, divergence and optical distortion
of the output beam. The concentrating cavity has two functions: one
is to effectively couple the pump source with the working
substance; the other is to determine the distribution of the
pumping optical density on the laser material, thereby affecting
the uniformity, divergence and optical distortion of the output
beam. . Both the working substance and the pump source are
installed in the concentrating cavity, so the advantages and
disadvantages of the concentrating cavity directly affect the
efficiency and working performance of the pump.
Features:
The solid-laser combined concentrating cavity has the advantages of
good laser mode, uniform pumping, high concentrating efficiency,
good cooling effect, reliability and durability, and long-term use
efficiency, and is widely used in the manufacture of medium and
small power pulsed and continuous lasers.
1) The concentrating cavity is composed of two parts of the upper
and lower cavities. The upper and lower cavities are each an
independent whole, which can be opened and closed freely. Only the
upper cavity can be uncovered when the lamp is replaced or
replaced. It is possible to carry out lamp installation and lamp
replacement without removing the other optical path components of
the laser or the entire concentrating cavity, without re-adjusting
and debugging the light; uncovering the upper cavity during the
installation of the crystal can conveniently observe the
installation of the crystal. It is convenient to adjust the
position of the crystal. In this case, it is also convenient to
observe and debug the visible light source. It has the
characteristics of convenient installation, accurate positioning
and simple operation.
2) The geometric parameters of the reflecting surface of the
concentrating cavity are close to the theoretical value, the mirror
gold plating is fine and uniform, the concentrating effect is good,
and the conversion efficiency is high.
3) The concentrating cavity cooling is to first cool the crystal
and then cool the reflecting cavity and the pump lamp, which can
effectively protect the crystal, extend the life of the crystal and
have a good cooling effect.
