Abstract

The utility model relates to a device for producing a laser crystal and discloses an iraurite crucible for producing a laser crystal. The iraurite crucible is composed of a crucible wall and a crucible bottom; the diameter and height of the iraurite crucible are both 150mm; a crucible bottom thickening region is welded at the center of the crucible bottom of the iraurite crucible; the thickness of the crucible wall is 2.0-2.4mm; the crucible bottom thickening region is a circle with the diameter of 45-55mm and the thickness of 2.5-3.5mm. The iraurite crucible has the beneficial effects that after the design of the iraurite crucible is improved, the thickness of the crucible wall is 2.2mm, so that the crucible begins to leak after being used for more than seven times; part of the crucible bottom is thickened by 3mm, so that the distortion deformation condition of the crucible bottom can be remarkably overcome; the service cycle of the iraurite crucible can be prolonged to seven times; the current iraurite crucible with the wall thickness of 2.2mm, the bottom thickness of 3mm and the partially thickened bottom can save 500g of iraurite as comparison with the traditional iraurite crucible and can be used for more than seven times, so that the production cost is reduced.

Description

A kind of Iridium Crucible for the production of laser crystals

Technical field

The utility model relates to a kind of device of producing laser crystals, and what be specifically related to is a kind of Iridium Crucible for the production of laser crystals.

Background technology

Yttrium aluminum garnet referred to as YAG, chemical formula is Y ₃al ₅o ₁₂, be by Al ₂o ₃and Y ₂o ₃reaction by a certain percentage forms, and belongs to isometric system, has garnet structure.Obtain neodymium-doped yttrium-aluminum garnet (Nd:YAG) with neodymium doping, Nd:YAG has good spectrum property, high optical quality, the low threshold value of high gain, there are lower photoelastic constant, higher mechanical hardness, and the advantage such as gratifying thermal parameters, thereby it is from find it is the most popular solid statelaser material so far always.The running that laser apparatus take Nd:YAG crystal as core parts can be realized the various ways such as continuous and pulse at ambient temperature, can realize frequency multiplication, thereby be widely used in every profession and trade.

At military aspect, Nd:YAG crystal, as the operation material of the most general solid statelaser of application, becomes the pillar of military Solid State Laser technology, and current 90% the military solid statelaser of exceeding is using Nd:YAG crystal as operation material; At medical field, Nd:YAG laser medical equipment is also by a large amount of application, and medical Nd:YAG laser apparatus is widely used at the aspect such as surgical operation, beauty treatment, particularly treats skin-color disposition disease, have wound little, heal, without distinct advantages such as scars; In industrial aspect, because obtaining high power laser light output, Nd:YAG crystal is widely used in materials processing industry, as automobile component processing industry, laser welding industry etc.; Aspect scientific research, solid statelaser is widely used in scientific research, as laser isotope is measured, laser chemistry, and laser guidance etc.; At present, in the occasion that needs superpower, high-energy, Q-switch and locked mode ultra-short pulse laser, Nd:YAG crystal is also first-selected working-laser material.

Taking up with induction heating of Raw of induction furnace YAG crystal growth all will be used Iridium Crucible, but iraurite is as noble metal, price is high, is in induction furnace growth apparatus, to be worth proportion the best part the important component part of cost in i.e. induction furnace YAG crystal growth.Since 2010, iraurite price started quick rise, the use of how to save iraurite in process of growth, and the effect of utilizing that how to improve iraurite is the problem that company must will solve, and is also the key reducing production costs.

Our company is used iridium pot as in induction furnace YAG serial crystal process of growth, Iridium Crucible is the main accessory that takes up raw material, induction heating, the Iridium Crucible of prior art as shown in Figure 1, in use procedure, there is iraurite volatilization in Iridium Crucible during due to high temperature, the distortion of Iridium Crucible wall, Iridium Crucible bottom warp equal loss, after loss acquires a certain degree, there is seepage or perforation phenomenon in Iridium Crucible.After using according to company's Iridium Crucible, follow the tracks of, find the current Iridium Crucible maintenance reason using, 80% comes from bottom warp, particularly the distortion of center D50 region.Observe still iridium pot in use, find that Iridium Crucible is used 3-4 all after date, bottom starts to occur torsional deformation, thereafter after each use, Iridium Crucible deformation of bottom is more serious, but the distortion of Iridium Crucible wall is also not obvious, when most of iridium pot bottom seepage occurs (general life cycle is 6 times), Iridium Crucible wall is still intact, therefore considers Iridium Crucible to improve.

Utility model content

The purpose of this utility model is the problem existing in Iridium Crucible use procedure in above-mentioned prior art, simultaneously for reducing production costs, enhance one's market competitiveness, a kind of Iridium Crucible for the production of laser crystals is provided, problem that can effective solution Iridium Crucible deformation of bottom reduces costs by saving Iridium Crucible simultaneously.

For arriving above-mentioned technical purpose, the utility model is achieved through the following technical solutions: a kind of Iridium Crucible for the production of laser crystals, formed by (2) at the bottom of crucible wall (1) and crucible, described Iridium Crucible diameter is 150mm, height is 150mm, it is characterized in that: at the bottom of described Iridium Crucible crucible, (2) center is welded with thickened area (3) at the bottom of crucible, and the thickness of described crucible wall (1) is 2.0 ~ 2.4mm, thickened area at the bottom of described crucible (3) is that diameter is 45 ~ 55mm, the circle that thickness is 2.5 ~ 3.5mm.

As preferred version of the present utility model, the thickness of described crucible wall (1) is 2.2mm.

As preferred version of the present utility model, thickened area at the bottom of described crucible (3) are that diameter is 50mm, the circle that thickness is 3mm.

In sum, adopt after the technical solution of the utility model, can effectively realize following technique effect: the crucible wall thickness after Iridium Crucible improvement design is 2.2mm, can use and just start to occur above seepage 7 times, and at the bottom of crucible, local thickening 3mm can obviously improve torsional deformation situation at the bottom of crucible, and can improve Iridium Crucible life cycle to 7 time, can think at present wall thickness 2.2mm, base thickness 3mm, the local thickening in bottom Iridium Crucible, can more original Iridium Crucible structure save iraurite 500g, and can guarantee that Iridium Crucible access times are more than 7 times, reduce production cost.
