Wherein, the first reflecting mirror and the second reflecting mirror are identical fused silica material eyeglass, receive original laser light
Beam is coated with 45 ° of total reflection films on one side, can change the direction of propagation of incident light.
In practical applications, the wavelength of fused silica material be 355nm, transmissivity 1.476, absorptivity is low, thermal expansion
Coefficient is small, and damage threshold is high, the application being suitble in high power laser light.
In a particular application, the position of the first reflecting mirror and the second reflecting mirror, control can be adjusted by arbitrary mode
Original laser beam emissions are divided the incident angle of plain film to level-one, to control the reflectivity of level-one light splitting plain film.
In one embodiment, the first reflecting mirror and the second reflecting mirror are mounted on two-dimension adjustment microscope base；
Wherein, two-dimension adjustment microscope base controls original laser light for adjusting the position of the first reflecting mirror and the second reflecting mirror
Beam is to preset incident angle, and transmitting is into level-one light splitting plain film.
In embodiments of the present invention, presetting incident angle is 15 °~20 °.
In a particular application, enable the first reflecting mirror and original laser light beam anti-in 45 ° of angles, the second reflecting mirror and through first
Original laser light beam after penetrating mirror reflection is also in 45 ° of angles, so that original laser light beam is in the first reflecting mirror and the second reflecting mirror
In for total reflection, between then reflect level-one light splitting plain film relative to the second reflecting mirror 15 °~20 ° of original laser light beam
One angle is placed, such as 17 °, then the original laser light beam that the second reflecting mirror can be made to reflect is with 17 ° of incident angle, transmitting
Into level-one light splitting plain film.After this, then the position of the first reflecting mirror and the second reflecting mirror is adjusted, then can enables default incidence
Angle is any one angle between 15 °~20 °.
In embodiments of the present invention, level-one is divided plain film 13, for original laser light beam to be divided into the reflected beams and first
Transmitted light beam, and the reflected beams are emitted with default incident angle into secondary light-splitting plain film；
In a particular application, between 15 °~20 ° of the reflected beams secondary light-splitting piece reflected relative to level-one light splitting piece
An angle place, such as 17 °, then the reflected beams can be emitted with similarly presetting incident angle to secondary light-splitting plain film
In.
In embodiments of the present invention, secondary light-splitting plain film 14, for the reflected beams to be divided into laser detection light beam and second
Transmitted light beam, and by laser detection beam emissions into detector, carry out quality testing；Wherein, laser detection light beam, as original
The quality testing sample of beginning laser beam.
In a particular application, level-one light splitting plain film and secondary light-splitting plain film are also identical fused silica material eyeglass, packet
Include receive light beam, the reflected beams and transmitted light beam while, and level-one light splitting plain film and secondary light-splitting plain film reflection
Coefficient is identical with transmission coefficient, therefore level-one light splitting plain film and secondary light-splitting plain film light splitting ratio having the same.
As a result, after level-one light splitting plain film separation reflected beam energy obtained much smaller than the first transmitted light beam energy and
Original laser beam energy, and laser detection beam energy obtained is much smaller than the second transmission after the separation of secondary light-splitting plain film
Beam energy and reflected beam energy.
In practical applications, using fused silica material eyeglass as light splitting plain film, level-one light splitting plain film and two may be implemented
The reflectivity of grade light splitting plain film is much smaller than its transmissivity.Since the wavelength of fused silica material eyeglass is 355nm, transmissivity is
1.476, therefore, according to fresnel formula, level-one is divided the reflectivity of plain film and secondary light-splitting plain film 4% or so.
In one embodiment, secondary light-splitting plain film is also used to emit the second transmitted light beam into detector, carries out matter
Amount detection；
Wherein, the second transmitted light beam, as the quality testing sample of original laser light beam, the second transmitted light beam and laser inspection
Surveying light beam has different decaying magnitudes.
In a particular application, the reflected light isolated in level-one light splitting plain film, has had lesser energy, using
It after secondary light-splitting plain film is divided, can apply in the detector of different size, as quality testing sample, obtain original
The quality measurements of laser beam, so that the application range of expansion of laser light beam splitting mean, improves resource utilization.
For example, it is assumed that the reflectivity of level-one light splitting plain film and secondary light-splitting plain film is 4%, transmissivity 96% then reflects
The energy of light beam is the 4% of original laser beam energy, and the energy of laser detection light beam is the percent of reflected beam energy
4%, it is the 0.16% of original laser beam energy；The energy of second transmitted light beam is percent the 96% of reflected beam energy,
It is the 3.84% of original laser beam energy.Then original laser light beam can be applied to the beam detection of 0.16% attenuation ratio,
Second transmitted light beam can be applied to the beam detection of 3.84% attenuation ratio.
As shown in Fig. 2, in embodiments of the present invention, above-mentioned laser beam separator 10 can also include beam-shrinked mirror
15。
In embodiments of the present invention, beam-shrinked mirror 15 for receiving laser detection light beam, and adjust the straight of laser detection light beam
Diameter；
Or, for receiving the second transmitted light beam, and adjust the diameter of the second transmitted light beam.
In a particular application, laser beam spot sizes can be reduced certain multiple by beam-shrinked mirror, and not change laser light
Beam divergence angle, to make detector of the laser beam suitable for different light-receiving areas.
Laser beam separator provided in an embodiment of the present invention is swashed by the first reflecting mirror and the second reflecting mirror by original
Light light beam is emitted in level-one light splitting plain film with default incident angle and carries out first time separation, then by secondary light-splitting plain film to one
The reflected beams that grade light splitting plain film reflection issues carry out second and separate, wherein the reflected light after the separation of level-one light splitting piece, hair
Incident angle when being mapped to secondary light-splitting plain film is still default incident angle, the laser detection light after finally separating second
Beam emits as the quality testing sample of original laser light beam into detector, carries out quality testing.Since level-one light splitting is flat
The reflectivity of piece and secondary light-splitting plain film is lower, then reflected beam energy obtained is much smaller than the first transmission after separating for the first time
Beam energy and original laser beam energy, and laser detection beam energy obtained is saturating much smaller than second after separating for the second time
Irradiating light beam energy and reflected beam energy, therefore, the laser beam separator that the embodiment of the present invention proposes have sufficiently small
Light splitting ratio improves light splitting precision, and the first reflecting mirror, the second reflecting mirror, level-one light splitting plain film and secondary light-splitting plain film are equal
The mode that laser beam will not be changed is avoided and is impacted to the quality of laser beam and its quality testing analysis.
