Abstract
The utility model discloses a flash lamp pumped repetition frequency laser without cooling and entirely solidification, which is composed of a pyramid cover, a pyramid positioning seat, a pyramid prism, a pyramid seat, a Q-switch, a Q-switch sleeve, a copper sleeve, a left plug, a O-ring, a xenon lamp, a laser wand, an oval condenser chamber, a base, a right plug, an output mirror seat, an output mirror housing, an output lens and an output lens cover, which is characterized in that the pyramid prism is adopted to be the laser resonator cavity mirror in which the angular point is disposed on the laser wand axis. One short section of bonding laser rod without the adulteration of the formation of YAG rod and integration processed condenser chamber are respectively grown on both ends of Nd: YAG rod. With simple practical structure and convenient usage, the utility model is characterized in the high stability, high efficiency, high repetition rate, with no cooling required, good beam quality, non-drifting optical axis and so on.
Description
Technical field
The utility model relates to laser field, is specifically related to the full flash lamp pumping repetitive frequency laser that solidifies of a kind of nothing cooling, can be applicable to fields such as industry, national defence, medical treatment, scientific research.
Background technology
Seriously cause the not even problem of bright dipping of beam quality variation in order to solve laser repetition rate when operation under no cooling condition because of thermal effect, Chinese patent CN200420084134.8 is with the Nd:YAG crystal, the YAG crystal diffusion bond of Q switching Cr4+:YAG and prism of corner cube is integrated, but be difficult to change Q switching, be inconvenient to select energy, and YAG crystal angle cone prism processing difficulties has limited its range of application greatly.
Summary of the invention
The utility model purpose is to provide the cooling of a kind of nothing the full flash lamp pumping repetitive frequency laser that solidifies, and is simple in structure, easy to use, have high stability, high efficiency, high repetition frequency, need not cooling, good beam quality, optical axis do not have characteristics such as drift.
In order to achieve the above object, the utility model is by the following technical solutions:
(1) adopt the completely reflecting mirror of prism of corner cube as laserresonator, realize even luminous effect, angle modeling effect can compensate the adverse effect of thermal effect to beam quality;
(2) adopt bonding rod technology, a bit of plain YAG rod of respectively growing at Nd:YAG rod two ends is used for fixing, and is beneficial to heat radiation, helps to reduce the plane rod end effect, improves pumping efficiency simultaneously;
(3) adopt integrated oval laser pump cavity technology, process again luggage respectively with traditional oval laser pump cavity two halves and join and compare, the precision height, the light gathering efficiency height is beneficial to heat radiation;
(4) oval laser pump cavity is between left plug and right plug, and left plug is between pyramid seat and oval laser pump cavity, and right plug is between oval laser pump cavity and outgoing mirror cover, and base is positioned under the oval laser pump cavity.Oval laser pump cavity many places have ventilation slot, can strengthen radiating effect.
The utility model compared with prior art has the following advantages:
(1) this laser adopts corner-cube prism resonant cavity, has very strong anti-imbalance ability, the error angle that allows as the prism of corner cube of total reflective mirror is up to ± 20 °, the prism central shaft can depart from chamber axle D/4 (D is the diameter of laser bar), itself and plane completely reflecting mirror can constitute exempts to debug resonant cavity, has overcome resonant cavity imbalance and cause the defective of laser fails easily fully;
(2) need not be air-cooled, the repetition rate height, good stability, optical axis does not have drift;
(3) simple and compact for structure, cost is low, easy to use.
Description of drawings
Fig. 1 is not for there being the full flash lamp pumping repetitive frequency laser structural representation that solidifies of cooling.
Wherein: 1-pyramid lid, 2-pyramid positioning seat, 3-prism of corner cube, 4-pyramid seat, 5-Q switch, 6-Q switch cover, the 7-copper sheathing, 8-left side plug, 9-O type circle, the 10-xenon lamp, 11-laser bar, the oval laser pump cavity of 12-, the 13-base, the right plug of 14-, 15-exports microscope base, 16-outgoing mirror cover, 17-outgoing mirror, 18-outgoing mirror lid
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Laser bar 11 and xenon lamp 10 place respectively on two focuses of oval laser pump cavity 12, and the light that assurance xenon lamp 10 sends is injected in the laser bar 11 after oval laser pump cavity 12 inner surfaces emission.Prism of corner cube 3 is the completely reflecting mirror of laserresonator, the angle overhead of prism of corner cube 3 on the axis of laser bar 11 and outgoing mirror 17 constitute together and exempt to debug resonant cavity.Oval laser pump cavity sidewall processes a lot of radiating grooves, is convenient to heat radiation.The laser pump cavity many places have ventilation slot, can strengthen radiating effect.But the copper sheathing auxiliary lamp at lamp two ends heat radiation.
Above technical scheme can realize a kind of simple and practical, has high stability, high efficiency, high repetition frequency, good beam quality, the full flash lamp pumping repetitive frequency laser that solidifies of the rift-free nothing cooling of optical axis, has broad application prospects.
