In order to realize above-mentioned technical purpose, according to the present invention, provide a kind of end face observer, for observing the laser amplifier end face hot spot of laser amplifier chain, it is characterized in that comprising: coupled end, rotating shaft and observation end; Wherein coupled end is configured to an external diameter first sleeve consistent with the internal diameter of amplifier, for end face observer is connected to laser amplifier; Wherein, coupled end is connected by rotating shaft with observation end, and rotating shaft is adjusted the angle between coupled end and observation end by rotation; Observation end comprises high-reflecting film, to utilize high-reflecting film that the hot spot situation of amplifier end face is reflected to original optical path.
Preferably, observation end comprises the second sleeve, to be connected with rotating shaft.
Preferably, the outside dimension of the second sleeve of observation end is identical with coupled end outside dimension.
Preferably, high-reflecting film is positioned at the outermost of the second sleeve of observation end, is 45 ° of placements with the longitudinal axis of rotating shaft.
Preferably, the reflectivity of high-reflecting film is greater than 95%.
Preferably, rotating shaft is stepless rotation shaft.
Preferably, rotating shaft has locking device, for locking the angle between coupled end and observation end.
Thus, for overcome can not directly observe hot spot and cause cannot accurate adjustment amplifier position and avoid the industrial accident of the laser wound eye that likely therefore occurs, the invention provides a kind of can be at the end face observer of original optical path External Observation laser amplifier end face hot spot situation, this observer can accurately be observed hot spot situation outward at original optical path.
