I.Introduction

The development of laser-cutting machines is a revolutionary progress in modern manufacturing. From early manual cutting to mechanical cutting and to present high-accuracy laser cutting, the cutting technology evolution has not only boosted productivity but also enlarged the boundaries of material processing.

In the whole course, the advent of laser cutters marked that modern manufacturing entered a brand-new era. By virtue of their unique work principles and prominent performance, laser cutting machines significantly changed the fabrication industry.

Laser, an extremely fine and highly concentrated beam of light, can heat materials into extremely high temperatures within a few seconds to achieve precise, rapid and contactless cutting.

This cutting method is applicable to multiple materials, including metals, plastic, glass and wood, without the restrictions of material shapes and processing complexity, which greatly expands the possibility of design and fabrication.

Therefore, the laser cutting machine is both an important tool for modern manufacturing and a pivotal cutting technology that boosts industrial consistent innovation and development.

In the following content, I will introduce the development history of the laser cutting machine according to the timeline in which its working principles, applied sectors and future trends will be discussed so as to provide you with a thorough introduction to how the magical machine changes manufacturing.

II.The Origins of Laser Technology

Early Concepts and Theoretical Foundations

The theory of stimulated emission by Albert Einstein in 1917:

Being traced back to the 1910s, the theory foundation of laser cutting technology came from the Stimulated emission theory proposed by Albert Einstein in his 1917 paper On the Quantum Theory of Radiation. Stimulated emission is the basic physical process of laser generation.

In stimulated emission, an atom that is already in an excited state absorbs a photon with energy equal to its transition energy, gets stimulated, and releases two photons with identical energy, frequency, phase, and polarization direction, which laid a solid and scientific foundation for laser cutting technology.

The first operational laser by Theodore Maiman in 1960:

American physician Theodore Harold Ted Maiman innovated the world's first ruby laser at Hughes Research Laboratories in the United States in 1960.

This is the first ruby laser that uses synthetic ruby as the gain medium. Maiman’s achievements proved the possibility of the real application of Einstein’s theory, which ushered laser technology into a new era.

Development of the First Laser Cutters

The first experiments with laser cutting in the early 1960s:

The development of laser-cutting machine started at the eaely 1960, when scientists were actively searching the posibility of using laser to cut accurately. The experiments then were mainly focusing on how to use the high-power density to cut materials, expecially for metals and non-metals.

Kumar Patel's work at Bell Labs and the first CO2 laser cutter:

Kumar Patel's work at Bell Labs fulfilled its role in promoting laser cutting machines. Invented by Patel in 1963, the first CO2 lasers, which boasted high efficiency and accuracy in metal cutting and welding, emerged as one of the most acceptable lasers in the industry.

The invention of the CO2 lasers marked the practical application of laser cutting technology, which laid a solid foundation for subsequent technology development and application expansion.

The early laser cutting experiments not only presented the great potential of laser in material processing but paved the way for applications in many sectors, such as medical care, communication and manufacturing.

As laser cutting technology develops, laser cutters have served as one of the most indispensable machine tools in modern manufacturing.
