Types of Lasers

There are many different types of laser medium:

  • Solid-State
  • Gas
  • Excimer
  • Fiber
  • Disc
  • Dye
  • YAG
  • Semi-conductor/Diode

There are similarities and differences between the different laser mediums, not only in their applications, but in their wavelength ranges, power output, heat output, and cooling needs.

Laser power output spans a very large range:

Low-powered lasers such as those found in laser pointers and disc readers generally have their own built-in cooling system, so they don’t generate enough heat to damage the components surrounding the laser. However high-powered lasers generate a massive amount of heat that must be removed from the laser system.

The best method for removing excess heat is using an external industrial laser process cooling system. There are many benefits to keeping a laser system cool.

Benefits of Laser Chillers

Maintaining precise wavelengths

Excess heat in a laser system increases the laser wavelength and compromises the laser’s performance. 

High output efficiency

Lasers require very precise specifications in order to perform accurately. An overheating laser can be dangerous, imprecise and make it difficult to point the laser with stability.

Maintaining desired beam quality

Strong beam focus is required for precise laser work such as engraving, cutting, drilling, and printing.  A fluctuating beam is dangerous and destructive.

Reducing thermal stress

Reducing the operating temperature can protect materials, equipment, reduce maintenance, and increase the lifetime of the laser system.

Lasers are an essential part of delivering high-speed, pinpoint accuracy in both general and specialized industrial applications. When it comes to these technologies, installing laser chillers for laser cooling provides incredible value to the operation.

There are many different types of chillers used in dozens of industries. Even though the applications may differ, the need for temperature control is consistent. Utilizing chillers keeps industrial lasers at constant temperatures; this allows the lasers to reach maximum performance. Lasers operate at extremely high temperatures. Temperature regulation removes heat from the system which prevents the overheating of critical components. Additionally, this temperature regulation drastically extends the lifespan of lasers.

Laser chillers are regularly used in a variety of applications including metallurgy, welding, thermal spray, polishing, spindle, laser cutting, induction heating and ovens, deep draw presses, grinding, fiber optics, and PCB drilling. Specialized applications include cosmetic treatments, military grade lasers, and medical technology treatments.

Let’s take a quick look at the specific benefits of using chillers for lasers:

Sustain Constant Laser Wavelength and Power

Output wavelength and power are quite temperature sensitive. Using chillers for lasers will keep these elements consistent. This will ensure reliable laser performance. Moreover, keeping wavelength and power well-regulated will increase the life of lasers.

Remove Waste Heat

As mentioned above, lasers generate significant heat output. Chillers sufficiently cool lasers to eliminate unnecessary waste heat. This ensures steady temperature, flow rate, and quality with laser equipment.

Achieve Desired Beam Quality and Prevent Vibrations in the Laser Head

In some laser applications like welding, uncontrolled heat rates commonly result in lowered beam quality and vibrations in the laser head. Proper temperature control maintains the shape and beam of the laser. This, in turn, reduces scrap rates.

Lessen Thermal Stress on the Laser System

Drastic changes in temperatures put a great deal of stress on operating systems. Using chillers to cool laser systems reduces this stress. That means significantly less defective productions and system breakdowns.

Achieve Higher Production Value

Laser systems are sensitive; the exceptional heat that lasers generate will most definitely lead to unexpected downtime, faulty parts, and lost profit if the proper temperature control steps aren’t taken.
