Description
Technical field
The present invention relates to field of laser device technology, more specifically to a kind of compact water cold stop.
Background technique
Diaphragm refers to the entity for playing restriction effect to light beam in optical system.It can be the edge of lens, frame
Or the screen with holes being especially arranged.It, which is acted on, can be divided to two aspects, limit light beam or limitation visual field (areas imaging) size.Optical system
The most diaphragm of middle limitation light beam, referred to as aperture diaphragm, the most diaphragm of limitation visual field (size), referred to as field stop.By upper
Known to, aperture diaphragm and field stop are both in kind.Determining the general rule of the aperture diaphragm of optical system is: from object point
The picture for seeing diaphragm or diaphragm, by wherein subtended angle it is the smallest that, to determine the aperture diaphragm of optical system.If subtended angle is minimum
Be certain diaphragm picture, then the diaphragm inherently aperture diaphragm.
In Optical Maser System, Space Coupling System is a kind of common coupled system, is generally used for the amplification system of laser
In system, laser amplifier system basic functional principle is exactly that signal light passes through the gain media that can generate laser, is provided by outside
Pumping light stimulus, make to be amplified by the signal light intensity of gain media.Therefore as the coupling in laser amplification system
The stability for closing structure is just particularly important, and directly affects final amplification laser intensity and pointing stability.
Laser amplifier system mainly include signal light collimation coupled system, gain media, pumping coupling system composition, and its
Middle signal has the final output power stability and pointing stability of laser optically coupling to the structural behaviour of gain media very big
It influences, this pump light for being mainly reflected in gain media spilling can be beaten on signal optical coupling lens, to constantly heat eyeglass
Lead to signal light off-target coupling position.Filtering pump light method based on dichroic mirror be by plated film lens pump light and
Signal light distinguishes, but dichroic mirror must be inserted into optical path with 45° angle degree, larger to system requirements space spacing, and dichroic mirror
Thickness can cause signal light that deviation occurs before entering laser gain medium；Coupling optical path is thus inserted perpendicularly into using heat absorption diaphragm
It is a kind of New Measure saved space, do not interfere optical path, and in high-power coupled system, it is necessary to using dissipating for more strength
Hot mode takes away the heat that pump light generates, and in addition the structure size of diaphragm also will have a direct impact on signal coupling focusing lens
The selection of parameter, and common diaphragm is only capable of playing light-blocking effect, can not take away heat, or the device by multiple dispersions
To realize above functions, structure size is larger, can not be competent in some occasions using short focus Lens Coupling for assembling.
Summary of the invention
1. technical problems to be solved
