Classification And Function of Laser Generator

Classification and function of laser generator

The laser generator of a laser cutting machine is the core component of the entire system, and its function is to produce a high-energy-density laser beam for cutting, engraving, or marking various materials. The high energy density of the laser beam can heat the material locally to its melting point or boiling point in a very short time, thereby achieving the cutting or removal of the material.

The laser generator mainly determines the cutting speed, precision, cutting thickness, and applicable materials of the laser cutting machine.

Common laser generator brands include:

IPG (Germany): IPG Photonics is one of the world's largest fiber laser manufacturers, and its products are known for their high efficiency, high reliability, and high power. They are widely used in various industrial laser applications, including laser cutting. IPG lasers are generally more expensive, but their performance is stable and their lifespan is long.

Raycus (China): Raycus is a well-known domestic fiber laser manufacturer, and its products have an advantage in terms of cost-effectiveness. They have a high market share in the domestic market. Raycus lasers are slightly inferior to IPG in terms of performance, but they are more competitive in terms of price.

JPT (China): JPT is also a Chinese fiber laser manufacturer, and its product line is relatively comprehensive. In terms of power and price, it is similar to Raycus.

Maxphotonics (China): Maxphotonics is another Chinese fiber laser manufacturer, and it is characterized by providing customized solutions, making it suitable for some special application needs.

SPI (USA): SPI Lasers is a brand that focuses on high-power lasers and has advantages in certain specific industrial fields.

The differences between laser generators of different brands mainly lie in the following aspects:

Power: Different brands and models provide laser generators with different powers. The higher the power, the faster the cutting speed and the thicker the cutting thickness.

Beam quality: Beam quality is represented by the M² value, and the closer the M² value is to 1, the better the beam quality and the higher the cutting precision.

Efficiency: The efficiency of a laser generator refers to the ratio of laser output power to electrical energy consumption. The higher the efficiency, the lower the energy consumption and the lower the running cost.

Lifespan: The lifespan of a laser generator is usually measured in working hours, and the longer the lifespan, the lower the maintenance cost.

Stability: The stability of a laser generator refers to the stability of its output power and beam quality. The higher the stability, the more stable the cutting quality.

Price: The prices of laser generators from different brands and models vary greatly, which is closely related to factors such as power, beam quality, efficiency, and lifespan.

When choosing a laser generator, it is necessary to select a suitable brand and model according to specific application needs and budget. For example, for high-precision and high-efficiency applications, IPG's laser generator can be chosen; for applications with limited budget, Raycus or JPT's laser generator can be chosen. It is important to communicate with suppliers to understand the specific performance parameters of different laser generators, so as to make the best choice.
