Lasers are widely used in robotics. By using laser in laser measurement sensors, it can help robots achieve high-precision positioning, control and safety detection, while improving productivity and product quality.

In two core fields—printing plate-making and photovoltaic (PV) screen printing—the CTS Laser Engraving Module is gradually replacing the traditional film-based plate-making process. It has become the industry mainstream due to its advantages of high precision, high efficiency, and low cost.Core Work

Collimation refers to the degree to which a laser beam remains parallel as it propagates over distance. An ideal collimated beam has perfectly parallel edges and never diverges, with a divergence angle of exactly 0. However, this is impossible in reality and only exists in some science fiction movies where laser beams extend infinitely with a constant diameter. In reality, laser beams inevitably diverge, and when the distance to the laser is sufficiently large, its intensity may even follow an inverse square law.

The essential difference between a single mode laser and a multimode laser is that there is one and only one mode in the output beam of a single-mode laser, while there are multiple modes in the output beam mode of a multimode laser.

Laser engravers and cutters are commonly available nowadays. Many people use them to create all kinds of crafts to make homes sweeter, use them as gifts, or sell them to have an extra income.

Among all laser machines, fiber, CO2 and diode lasers are three types of laser engravers used commonly. But if you get confused about the differences between them, and which laser is perfect for you, you are not alone.In this article, we'll explain their techniques and clarify the differences between them.

Amid growing controversies over the environmental and health impacts of chemical herbicides, laser weeding has emerged as a game-changing black technology in smart agriculture, boasting "zero pollution, high precision, and intelligence." However, with a plethora of laser technologies available, a critical question looms for agricultural tech developers: Which laser should you choose?
 

Laser weeding is an innovative, chemical-free approach to agricultural weed control that uses high-energy light beams to destroy unwanted plants. Several laser types are currently used in this application, each with distinct advantages depending on the specific weeding scenario.
 

Lasers are basically classified into 5 types based on their active medium. They are

Semiconductor laser

Liquid-state laser

Gaseous-state laser

Solid-state laser

Metal Vapour laser

We will discuss some of these types in the upcoming parts of this article.

Lasers are commonly used in most trades, particularly construction, installations, and surveying. They are used to project vertical, horizontal (and sometimes both) lines in either green or red to acquire fast and accurate measurements over a long distance.
But, what is the difference between the colours red and green? Is there any practical advantage to using one over the other? The fact is, there is absolutely no difference when it comes to accuracy. Both are (pun intended) laser-accurate. Ultimately, the key differentiators between the two are price, brightness, visibility, and battery life.

Both semiconductor lasers and CO2 lasers create concentrated beams of light, usually used for cutting away material, but they work in drastically different ways. They generate power through two different mechanisms, and each type of laser can come in diverse subtypes and configurations. Still, both processes start with reliable electrical power delivered from a sophisticated power supply.
