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 optical fiber coupling output intent.
Background technology
Laser diode pump solid state laser device (DPL) is normally directly exported with window form, the DPL of this way of output is in use because light beam is directly output, limited dirigibility that laser instrument uses and and other use being of coupled connections between the instrument and equipment of DPL.
Traditional DPL optical fiber coupling output intent is to increase a coupling device in the outgoing mirror outside of DPL, with the light beam coupling by window output in optical fiber, be of coupled connections again and between the instrument and equipment of other use DPL, this method is regulated the coupling difficulty, long-time use occurs coupling efficiency easily and reduces, need readjust coupling, meanwhile increased DPL volume, weight and outward appearance incoordination.
Summary of the invention
The purpose of this invention is to provide that a kind of volume is little, reliability and the high laser diode pump solid state laser device optical fiber coupling 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 optical fiber coupling 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 of coupled connections by GRIN Lens and optical fiber, output is coupled light in the optical fiber, exported by optical fiber.
