Description
Technical field
The present invention relates to a kind of laser diode pump solid state laser device, particularly a kind of laser diode pump solid state laser device coupling fiber output intent.
Background technology
Laser diode pump solid state laser device (DPL) normally directly exports with window form, the DPL of this way of output is in use directly export due to light beam, limit dirigibility that laser instrument uses and and other use being of coupled connections between the instrument and equipment of DPL.
Traditional DPL coupling fiber output intent increases a coupling device outside the outgoing mirror of DPL, by the light beam coupling that exported by window in optical fiber, again and other use between the instrument and equipment of DPL and be of coupled connections, this method regulates coupling difficulty, long-time use easily occurs that coupling efficiency reduces, need to readjust coupling, meanwhile add the incoordination of the volume of DPL, weight and outward appearance.
Summary of the invention
The object of this invention is to provide that a kind of volume is little, reliability and the high laser diode pump solid state laser device coupling fiber output intent of coupling efficiency.
The object of the present invention is achieved like this, a kind of laser diode pump solid state laser device coupling fiber output intent, comprise: laser diode pump solid state laser device, optical fiber, it is characterized in that: laser diode pump solid state laser device is connected with coupling fiber by GRIN Lens, output is coupled light in optical fiber, exported by optical fiber.
Described GRIN Lens left side plating 1064nm part reflectance coating, GRIN Lens left side is plated 1064nm part reflectance coating and is formed outgoing mirror.
The output end face plating 1064nm full-trans-parent film of described GRIN Lens.
Described GRIN Lens Double End plating 1064nm full-trans-parent film.
Described GRIN Lens is fixed in joint, and joint is embedded in the housing of laser diode pump solid state laser device, and joint and SMA905 fibre-optical splice, to export light coaxial.
Advantage of the present invention is: because laser diode pump solid state laser device is connected with coupling fiber by GRIN Lens, output is coupled light in optical fiber, is exported by optical fiber.Simplify optical fiber and export coupled structure, overcome the shortcoming of traditional coupling scheme.Secondly, output window miniaturization, through engineering approaches and modularization, by being beneficial to standardized designs.
