Abstract

The utility model relates to a novel contact type laser crystal cutter which is used for a high-energy laser. The utility model uses silica cladded fiber (1) as a conductive piece for laser, fibers (3) on the head parts of both ends of the silica cladded fiber (1) are melted in a core hole of a quartz tube, and are respectively made into the coupling input end of the laser crystal cutter and the output end of a crystal cutter head, and coating layers (2) of the optical fibers (3) are stripped; the input end is assembled into a coupling head (5), and the utility model is provided with the special coupling head. An optical coupling heating source can be effectively controlled, the working temperature of the high-energy laser can be reduced, and the service life of instruments can be ensured. The structural strength of the tailor-made crystal cutter head (9) is high, the crystal cutter head (9) can continuously work with high temperature for a long time without damage, and thus, the use reliability of the high-energy laser can be ensured.

Description

The quartzy cutter of novel contact laser

The utility model relates to a kind of transmission superlaser device of (claiming light laser again), and is particularly a kind of as the quartzy cutter of novel contact laser that is coupled with high-energy laser and exports.

In superlaser is used, be mostly with silicon rubber cladded-fiber (being PCS optical fiber) or silica cladded fibre (being CVD optical fiber) transmission laser in the past.Though use PCS optical fiber cost lower, because the covering of this optical fiber and coating all are to make non-refractory of silicon rubber, its two ends are all very easily caused damage by the light laser calcination, the part that must cut damage again and again could continue to use, and causes many inconvenience to operation, and operating efficiency is extremely low; And during with CVD optical fiber, though can near the organic matter coating the two ends be peelled off, exempt from by the scorching hot scaling loss of light laser, because of the diameter of its silica fibre own is just very thin, also be difficult to bear burning for a long time of light laser.Moreover, optical fiber and contact laser jewel cutter head combine (or claiming coupling) position, the loss of light is very big, heating is serious, for a long time continuous firing.

The purpose of this utility model is can stand the high light calcination for the public provides a kind of, the quartzy cutter of novel contact laser not fragile, that be convenient to operate for a long time.

For ease of introducing, technical measures of the present utility model and its optimum implementation are comprehensively described in detail below in conjunction with accompanying drawing:

Fig. 1 is the overall structure schematic diagram of utility model;

Fig. 2 to Fig. 4 is several typical quartzy cutter head structure shape schematic diagram on its output termination;

Fig. 5 is the view of its coupled end head unit on the delivery of high-energy laser.

So-called quartzy cutter, being commonly called as exactly to the superlaser cutter made with quartzy material.It is laser transporting part that the quartzy cutter of this novel contact laser also is still with silica cladded fibre (1), different is, the optical fiber (3) that the two ends head of used silica cladded fibre (1) has been peelled off coating (2) is to melt in the core hole of the quartz ampoule that is contained in identical material, make the couple input and the quartzy cutter head output of the quartzy cutter of laser respectively, its input is must be coaxial molten being contained in the core hole of quartz socket tube (4) of optical fiber (3) that coating (2) are peelled off by termination portion, be fitted in the coupling head (5) whole input termination is coaxial again, the utility model become carry the laser knife of laser couplers.For ease of adjusting, its input can install in the core hole of a clamping sliding sleeve (8), then with the cone segments axle rank device of clamping sliding sleeve (8) in the corresponding taper hole of coupling head (5) core hole front end, mobile input, make its transfer to coupling head (5) on the best focus position place of the focusing lens (6) that installing, compressing clamping sliding sleeve (8) with a lock sleeve (7) more whole input termination be packed in the coupling head (5).Output in silica cladded fibre (1), the optical fiber (3) of peelling off coating (2) are to melt in the core hole that is contained in the quartzy cutter head made from quartzy material (9).Be about to be melt into one again after optical fiber (3) is inserted in quartzy cutter head (9) the core hole.Use for convenient, preferably at the sheath (10) of the supporting again stainless steel tube making of the rearward end of quartzy cutter head (9) body, this both had been convenient to the clamping to quartzy cutter head (9), can protect quartzy cutter head (9) again and exempt from by clashing and breaking.The needs that quartzy cutter head (9) can use according to reality are that the quartz ampoule of 1.5～10 millimeters of φ draws with the diameter, and its termination portion can be made into cone sphere shape or cone flat-headed, also can be apex partis petrosae splay end formula, can also be to be the cone elbow type.

The coating (2) that can not bear high temperature sintering has been peelled off at silica cladded fibre (1) the two ends position of the quartzy cutter of this novel contact laser, and its optical fiber (3) is that quartz ampoule (4) and quartzy cutter head (9) fusion identical with material is one, this just the has been equivalent to overstriking optical fiber at two ends, even make its calcination that stands light laser for a long time, also can not damage.Very convenient exchange of its couple input and adjustment, every cutter is carrying the coupling head that is adjusted to the Best Coupling state, can make the coupling light loss be relieved to minimum level, controlled the optically-coupled pyrotoxin effectively, so be contained in when using on the high-energy laser, all more much lower than dress with the temperature of other any laser knife, improved the working condition of high-energy laser greatly, guaranteed the service life of instrument, special quartzy cutter head (9) structural strength height, can stand the long-time continuous hot operation and can not damage, thereby guarantee the reliability that equipment uses.The quartzy cutter of this novel contact laser is not only applicable to the high-energy laser of Laser Processing and so on, and is particularly suitable for using on the Nd:YAG crystal bar laser therapeutic apparantus high energy laser medical equipments such as (being the YAG laser therapeutic apparantus).As long as unscrew the lock-screw (12) on the laser delivery (11) on the high-energy laser, the difform cutter head of the quartzy cutter of this new pattern laser that can more renew quickly.
