When choosing a laser engraver, it’s essential to understand the different technologies available. Lasers can be classified according to their laser class (depending on installation configurations and safety risks), but also by laser type.

Monochromaticityof laser

Diode lasers offer a number of distinctive features and benefits. Their main advantage is their energy efficiency: they convert electricity directly into light, thus reducing energy consumption and associated costs

The world of lasers is wide and complex, with a multitude of types on the market. The most common are fiber, CO2, gas and semiconductor lasers. Their uses vary, from marking and cutting to medical applications. Each type of laser has specific properties, determined by the wavelength of its beam and the amplification environment.

Characteristics of a laserin physics

Lasers have transformed many industrial sectors thanks to their precision, versatility and efficiency. Their use has become generalized and diversified. From a technical point of view, these processes require the use of a laser beam to alter the surface of various materials.

All in all, these specific characteristics make diode lasers the preferred choice for many applications, whether industrial, medical or communications.

Alexandrite lasers have several distinctive features. Their wavelength is 755 nm, enabling them to precisely target the melanin present in hair. In addition, their mode of action is predominantly pulsed, although they can also operate in continuous mode.

Fiber lasers are characterized by their use of optical fibers as the active environment. These lasers offer remarkable energy efficiency and high precision, making them a preferred choice for industrial and medical applications. One of the main advantages of fiber lasers is their ability to generate high-quality beams with excellent stability. This technology also makes it possible to perform complex operations such as precise marking, while minimizing energy losses. Fiber lasers are particularly appreciated for their robustness and extended service life, thanks to the use of robust, durable optical fibers. What’s more, their compact design and low maintenance requirements make them ideal for integration into a variety of industrial systems. Fiber lasers are therefore commonly used in sectors such as micromachining, laser engraving, materials processing and high-precision medical applications.

Applicationsof laser

Gas lasers are a category of lasers whose active environment is a gas. They can be made up of different types of gas, such as carbon dioxide (CO2), argon or neon. These lasers were discovered almost simultaneously with solid-state lasers, with major discoveries in the infrared (CO2 laser) and visible (helium-neon laser).

In terms of applications, gas lasers offer a wide variety of uses. In particular, they are used in materials processing and surgery, thanks to their ability to deliver high levels of power. They are also used in laser marking and bar code reading.

Secondly, the laser beam is coherent. In other words, the light waves are perfectly synchronized, all having the same frequency and moving in phase. This temporal and spatial coherence ensures high precision and concentration of energy at a precise point.

Characteristics of laserPDF

The laser beam has three main characteristics. Firstly, it is monochromatic. This means that its light consists of a single color, determined by a single wavelength. This wavelength depends on the laser environment, i.e. the material in which the light is emitted.

Finally, the laser beam is collimated. It is highly directional, with light beams running parallel to each other and propagating in a single direction. It is this characteristic that gives the laser its range and its ability to remain focused over long distances.
