Ultrafast Laser Chiller Escorts Ultrafast Laser Processing

What is ultrafast laser processing? Ultrafast laser is a pulse laser with pulse width of picosecond level and below. 1 picosecond is equal to 10⁻¹² of a second, the speed of light in air is 3 X 10⁸m/s, and it takes about 1.3 seconds for light to travel from the Earth to the Moon. During the 1-picosecond time, the distance of light motion is 0.3mm. A pulse laser is emitted in such a short time that the interaction time between ultrafast laser and materials is also short. Compared with traditional laser processing, the heat effect of ultrafast laser processing is relatively small, so ultrafast laser processing is mainly used in fine drilling, cutting, engraving surface treatment of hard and brittle materials such as sapphire, glass, diamond, semiconductor, ceramics, silicone, etc.The high-precision processing of ultrafast laser equipment needs a high-precision chiller to cool. S&A high-power & ultrafast laser chiller, with temperature control stability of up to ±0.1℃, can provide fast and precise temperature control for ultrafast laser, meet the operating temperature conditions of the ultrafast laser in time and ensure the stable output of ultrafast laser in picosecond time. It works with the ultrafast laser, making breakthrough achievements in the frontier of fine processing.

Chip wafer laser marking and its cooling system

Chip is the core technological product in the information era. It was born of a grain of sand. The semiconductor material used in the chip is monocrystalline silicon and the core component of sand is silicon dioxide. Going through the silicon smelting, purification, high temperature shaping and rotary stretching, sand becomes the monocrystalline silicon rod, and after cutting, grinding, slicing, chamfering and polishing, silicon wafer is finally made. Silicon wafer is the basic material for semiconductor chip manufacture. To meet the requirements of quality control and process improvement and facilitate the management and tracking of wafers in subsequent manufacturing testing and packaging processes, specific marks such as clear characters or QR codes can be engraved on the surface of the wafer or crystal particle. Laser marking uses high-energy beam to irradiate wafer in a non-contact way. While executing the engraving instruction quickly, the laser equipment also needs to be cooled by S&A UV laser chiller to ensure the stable light output and satisfy the high-precision marking requirement of wafer surface.From a grain of sand to silicon wafer then a complete chip, there is a very strict demand for the precision of the production process. Laser marking’s precision is inevitably linked to the precise temperature control solution. S&A chiller seems to be small in the complex and tedious process of chip production, but it is an important precision guarantee of the intermediate link, it is with the guarantee of countless detailed precision that the chip goes to a more sophisticated field.

S&A Chiller Temperature Control for Laser Cladding Technology

In the fields of industry, energy, military, machinery, remanufacturing and others. Affected by the production environment and heavy service load, some important metal parts of may corrode and wear. To prolong the work life of the expensive manufacturing equipment, parts of the metal surface of the equipment need to be treated early or repaired. Through the synchronous powder feeding method, laser cladding technology helps deliver the powder to the matrix surface, using high-energy and high-density laser beams, to melt the powder and some matrix parts, helping to form a cladding layer on the surface with performance superior to that of the matrix material, and form a metallurgical bonding state with the matrix, so as to achieve the purpose of surface modification or repair.Compared with traditional surface processing technology, laser cladding technology features low dilution, with coating well bonded with the matrix, and great change in particle size and content. The laser cladding technology usually applies to kilowatt fiber laser equipment. S&A chiller offers laser melting equipment with temperature control solution. With dual modes: constant temperature and intelligent control. Supports Modbus-485 communication. Achieving real-time communication between the laser cladding system and the chiller and monitoring the chiller’s working condition and modifying its parameters. The chiller also comes with over temp and flow alarm function, working with laser cladding equipment to treat or repair some important metal surface parts, meeting with demands of the parts for specific performance of material surface, which can save abundant precious metallic element and reduce production and operation costs of the enterprise.

S&A 10,000W Fiber Laser Chiller Applied to Shipbuilding

The industrialization of 10kW laser machines promotes the use of ultrahigh-power fiber laser cutting machines in the thick sheet metal processing field. Take the ship production as an example, demand is strict on the precision of the hull section assembly. Plasma cutting was often used for rib blanking. To ensure the assembly clearance, cutting allowance was first set on the rib panel, then manual cutting was made during on-site assembly, which increases the assembly workload, and prolongs the whole section construction period. 10kW+ fiber laser cutting machine can ensure high cutting precision, without leaving the cutting allowance, which can save materials, reduce redundant labor consumption and shorten the manufacturing cycle. 10kW laser cutting machine can realize high-speed cutting, with its heat affected zone smaller than that of the plasma cutter, which can solve the workpiece deformation problem. 10kW+ fiber lasers generate more heat than normal lasers, which is a severe test for cooling and temperature control device. S&A CWFL-40000 chiller can be used for cooling 40kW fiber lasers, with dual temperature control system, simultaneously cooling the fiber laser and its head, intelligent monitor on required cooling power, and segment control of compressor operation as needed. It rises to the challenges of the fiber laser to its support equipment. To promote the widespread use of fiber lasers in aerospace, shipping, automobile, and energy equipment manufacturing, S&A chillers provide stable and reliable cooling.
