The beneficial effect that the utility model is compared with prior art produced is:
This laser intensity booster is that multiple laser is merged into beam of laser, makes light intensity export energy and strengthens.
This laser intensity booster can make former laser generator be export energy to improve an order of magnitude, concrete increase number bear light intensity depending on intensity and the material that is anti-, that reflect of former light intensity ability relevant.
The principle of this laser intensity booster be light by the parallel transparent body time, through birefringence, the light path of light can produce displacement to a certain degree.
The design proposal of this laser intensity booster is that the parallel laser of multi beam aggregates into beam of laser by the parallel transparent body.
The design mainly optically focused cone of this laser intensity booster, optically focused cone is the vertex of a cone of N number of symmetrical plane composition and the transparent body at the bottom of N number of parallel cone corresponding to vertex of a cone plane mainly.The numerical value of N is determined by the size of laser generator.The center line at the vertex of a cone and the cone end is main axis, and main axis and the vertex of a cone are perpendicular to the circular flat of main axis with the point of intersection of boring the end, and the size of circle is identical with the spot size of laser, and each corresponding flat of main axis and the vertex of a cone (or cone end) has an equal angle.The size of angle is determined to reduce reflection ray to increase the light of refraction to greatest extent, to greatest extent close to main axis when the size of cone reflects from the cone end with refracted ray, to reduce the spot diameter of synthesis light.
Spot diameter as synthesized light beam is excessive, by biconvex lens, spot diameter is diminished, and the energy density of light is increased.
This laser intensity booster advantage is: export with existing laser instrument on the basis of energy, increase the output energy of an one or nearly order of magnitude.Current Development of Laser Technology, the output energy increasing by an one or nearly order of magnitude on developed basis too.
Based on optically focused cone, the laser generator of additional N+1 portion equifrequency.Specifically: place a laser generator on optically focused cone main axis, with optically focused cone main axis for the center of circle, around the laser generator concentric circles of main axis being placed N portion equifrequency in the direction being parallel to main axis.
When N+1 portion laser generator sends laser, the laser that laser generator on main axis sends is with rectilinear propagation, and the laser that the N portion laser generator on main axis concentric circles sends, after twice refraction of optically focused cone, make this N restraint laser and be all aggregated in around the laser on main axis, and be parallel to main axis laser, and be combined into a branch of hot spot, obtain the laser beam more strengthened than former single laser beam, then diminished by combination laser hot spot by biconvex lens, energy density increases.
This laser intensity booster is reasonable in design, structure is simple, safe and reliable, easy to use, be easy to safeguard, have good value for applications.
