Czochralski Crystal growth method and growth furnace

Pulling method is currently the most widely used industrial crystal growth method, through the crucible hanging above the seed crystal, slowly rotating pulling upward from the melt to crystal growth, crystal size, growth rate accurately controlled, the growth process can be directly observed monitoring, flexible and variable temperature field conditions, to match different kinds of crystal growth needs, can be applied to growth, different category Crystals of different sizes.
Advantages:
1. With wide applicability, it is the most widely used growth mode in industrial production；
2. The temperature field conditions are flexible and suitable for different kinds of crystals. (The appropriate temperature field and growth process conditions can be adjusted according to the different physical properties of growing crystals);
3. The growth process is visible; (The crystal growth process can be observed through the observation window, which is convenient for process monitoring and process adjustment)；
4. It can grow crystals with diametral range of 10-100mm and isometrical length of over 300mm. (Match different crucible);
5. Crylink adopts the lifting method to grow dozens of series of crystals, including: rare earth or transition metal ion doped YAG series,YAP series, silicate series, sapphire series, vanadate series, niobate series, borate series and dozens of crystals.

Temperature gradient crystal growth furnace

The method is through the use of special heating element, form a stable temperature gradient in the longitudinal direction, the built-in seed crystal at the bottom of the crucible, so as to realize the crystal growth of crystals inside the crucible from bottom to top Growth process, the method of crucible let stand motionless, internal melt natural convection, interface easier to form stable growth, the growth of high quality crystal.
Features：

  • The gradient stability of temperature field is good;
  • High temperature control stability, temperature control precision 0.1；
  • The stability of crystal batch growth is good；

It is often used to grow Ti:sapphire, ruby,V:YAG and other crystals with high doping concentration and high doping ion uniformity.

Bridgman-Stockbarger method crystal growth furnace

The method is in the growing region to build a stable temperature gradient suitable for crystal growth, and then slowly downward movement, the crucible through the growing region, makes the material within the crucible of the grow slowly melting crystallization growth in this area, this method breaks through the ladder method fixed temperature zone of restrictions on the size of crucible, can grow larger, longer crystal crystal height.
Features：

  • Good stability；
  • Good flexibility, can match different crucible, grow different size crystal；
  • Crystal billets with larger diameter and higher height can be grown；
  • It can be used to grow crystals with a diameter of 35-200mm and a height of 50-100mm；

Crylink has successfully grown fluoride series crystals, such as MgF2, LiF, BaF2, CaF2, CeF3, etc., and used for batch growth of fluoride series crystals with diameters of 6 inches.

Cutting

Single wire cutting machine

Through a single high-speed and stable reciprocating diamond line fixed in the working range of the crystal billet for precision cutting; Often used for large crystal billet directional cutting, opening; Wire cutting through the cutting line to cut crystal, crystal force is small, the cutting process is gentle, not easy to crack.

  • Large working range：500*500*500mm;
  • Cutting reaches high precision：±0.05mm；
  • Accuracy of rotation angle：＜0.1°

Multi-wire saw

Through a number of high-speed and stable reciprocating diamond line fixed in the working range of the crystal blank for precision cutting, in its working range, a time can be cut dozens to thousands of pieces of the same thickness of the product, so it is often used for rapid precision processing of large quantities of products

  • Large working range：800*500*500mm;
  • Cutting reaches high precision：±0.05mm；
  • Batch capacity：~3000 pcs/day

Coating

Crylink focuses on the development and production of strong laser (super super fast and short) optical films and optical components, with thermal evaporation Electronic evaporation (E-Beam) and ion-assisted deposition (IAD) are four specialized high performance coating machines for high intensity laser optical films, which are equipped with ultrasonic cleaning equipment. By optimizing the film design and evaporation process, laser optical film plating can be realized in the range of ULTRAVIOLET 266 nm – infrared 5 um, which can be used for high reflectivity (HR) coating of resonator cavity Broadband HR and partial reflection (PR) coated laser harmonic separator dichromatic and polarized optical films.

In addition, we offer antireflection (AR) dual-band and tri-band AR laser film broadband Antireflection (BBAR) and metal coating with uV-visible-infrared spectrophotometer laser damage testing system (1064/1535/2940nm) laser plane interferometer friction and wear testing machine Optical microscope ULTRA hd CCD industrial imager High and low temperature aging box and other equipment to ensure product quality.
