Description
The invention belongs to a kind of solid laser oscillation-amplifier of novel efficient.
Laser amplifies and generally all to adopt discrete laser oscillator and amplifier to piece together to realize in the prior art, so need two cover lamps, laser bar, pump cavity.In order to obtain the output of high quality beam, often take the drive manner of little mode volume at oscillator stage.The major defect of this traditional vibration-amplification system be bulky, efficient is low.
The objective of the invention is to make a kind of laser head, a kind of novel efficient solid laser oscillation-amplifier that adopts cross-prism cavity and a small amount of additional device to constitute by a pumping lamp, two laser bars.
The prior art that the present invention is had reference significance is listed below:
" the crossed nicols telescope laserresonator " of (one) 1984 year the 8th interim state " optics journal " announcement.The laser that adopts this laserresonator to make has high mechanical stability, good beam quality (near field is solid, far field reach diffraction limit) simultaneously, the optical quality of laser bar is required low all advantages, and its shortcoming is less than normal at the application occasion output energy that has.
" the single-lamp pump double stick laser amplifier " that 613 research institutes of state Ministry of Aeronautics Industry are introduced in (two) 1984 years 11 months.The advantage of this amplifier is simple in structure, high efficiency.Its shortcoming is: what the laser oscillator of this amplifier adopted is parallel plane formula resonant cavity, and adopts right-angle prism (D II-180 °) to realize vibrating-coupling of amplifier.
The solution of the present invention essence is the advantage of comprehensive above-mentioned crossed nicols telescope laserresonator and single-lamp pump double stick laser amplifier, structurally they is organically combined, and has made a kind of novel, high efficiency solid laser oscillation-amplifier. This vibration-amplifier has high mechanical stability, good beam quality, improved the efficient of the device in the prior art, greatly increased the energy of Output of laser, simultaneously, the optical quality of laser bar wanted Ask not high, the acquisition of above-mentioned all good result is by taking the scheme corresponding to the part of the feature in the claim 1 to solve.
Most preferred embodiment of the present invention is shown in accompanying drawing 1 and accompanying drawing 2, and identical numeral shows identical or corresponding part among the figure.The laser head of a solid state laser (10) is made up of oscillator laser bar (11), amplifier laser bar (31), pumping lamp (13) and the pump cavity (12) of parallel installation, and the mutual alignment between them is different and different with the section configuration of pump cavity.These section configurations can be that a) single clam shell shape intersects circle, b) crossing round, the c of two clam shell shapes) bielliptic(al) (these three kinds of shapes all adopt the pump cavity of reflection type mirror).D) single cylindrical (diffuse reflection type pump cavity) shape.
Crossed nicols resonant cavity laser oscillator (20) is by laser head (10) and right-angle prism (D
II-180 °) (21), (22), medium polarizer (23) form, and can add corresponding element when requiring the running of q-operation or locked mode in the chamber.Can realize q-operation when putting into electrooptic crystal (24) in the accompanying drawing 1.The logical optical surface that the right-angle prism of two total internal reflection surface is arranged can be the plane, concave spherical surface and protruding sphere, can constitute crossed nicols unsteady cavity-comprise crossed nicols telescope laserresonator, stable cavity chamber and metastable resonators respectively with their various combination, promptly intersect POLO (Porro) prism cavity.The crest line azimuth of prism (21), (22) look laser operation mode-comprise continuously, pulse, accent Q, locked mode and different modes of emplacements is arranged.Generally all intersect, because it is such configuration makes laser oscillator that very high mechanical stability be arranged, less demanding to the optical quality of laser bar.When the parameter of prism (21), (22) and laser bar (11) etc. satisfied crossed nicols and looks in the distance the chamber, the laser beam of acquisition can be single transverse mode, and promptly the near field is solid, and the far field can reach diffraction limit.Can consult 721 pages of " optics journal " 1984 the 8th phases about the look in the distance detailed description of cavity laser of crossed nicols.
The way of output of cross-prism cavity laser oscillator has two kinds, and (27) are the axial output beams of oscillator in accompanying drawing 1, and (26) are the side direction output beams of oscillator in accompanying drawing 2, all obtain from (23) transmission of medium polarizer or reflection.The medium polarizer also is retained in chamber inner light beam (25) reflection or a transmission part (26) or (27) in the resonant cavity to keep vibration.
For axial output beam (27) shown in the accompanying drawing 1, the corner cube prism (or being called prism of corner cube) (32) that the present invention adopts logical light beam surface to be coated with anti-reflection film is coupled, it can inject light beam (33) after the reflection to amplify rod (31) impinging perpendicularly on light beam (27) skew one segment distance on (32) logical optical surface through three total internal reflections just, and the realization of this point is by means of the rotation of prism of corner cube and move and realize.As shown in Figure 3, but light beam is dropped on each line of demarcation, this prism has fabulous mechanical stability, event is very high with the mechanical stability of cross-prism cavity laser oscillator-amplifier that this coupled modes are formed, and the overall dimension of this prism can intercept by actual needs.
For axial output beam, the present invention also has a kind of right-angle prism (D that adopts logical optical surface plating anti-reflection film
II-180 °) (35) scheme of being coupled, see accompanying drawing 4, the total internal reflection that utilizes prism is light beam (27) skew one segment distance that impinges perpendicularly on (35) logical optical surface, light beam (33) after the reflection be able to be incided amplify rod (31), but this structure only has high mechanical stability in one direction, yet is still an adaptable scheme of the present invention.
For the side direction output beam (26) shown in the accompanying drawing 2, the present invention adopts a plane completely reflecting mirror (36) to be coupled, its position can be reflected into the light beam (26) that incides above it light beam (33) and make (33) enter amplification rod (31) fully just, for example works as medium polarizer (23) and uses K
9When glass is done base plate, laser for 1.06 μ, light beam (26) should be 33.5 ° to the incidence angle of speculum (36), this plane mirror should have the total reflection film under the regulation incidence angle condition, obviously, this coupled modes are limited to the characteristics of plane mirror, and the mechanical stability of coupling is relatively poor, yet this remains adaptable scheme of the present invention.
Laser bar (31), pumping lamp (13) and pump cavity (12) constitute amplifier of the present invention, yet pumping lamp (13) and pump cavity (12) are again the parts of oscillator, lamp of this usefulness, a pump cavity, the single-lamp-double-rod laser head of pumping oscillating rod (11) and amplification rod (31) makes the structure of whole vibration-amplifier become compact simultaneously, and efficient is improved, and Laser Power Devices are simplified.
Through amplifying the light beam (34) after rod amplifies, except that the characteristic that keeps oscillator output beam (26) or (27), energy has increased greatly.Accompanying drawing 5 is that the present invention is vibrated-output that amplifier experiment obtains and the relativeness curve of input.
If laser oscillator is changed into other forms, the present invention to single pumping laser vibrate-coupling principle of amplifier remains suitable.For example after replacing prism (21) and (22) with plane or sphere completely reflecting mirror, as long as at the wave plate of medium polarizer by the side adding output coupling of rod, system still can turn round, but three major advantages of most preferred embodiment of the present invention have not just existed.
