When Laser Invented: The Revolutionizing Invention

In today's world, laser is something that we come across almost every day, from laser pointers to laser surgery, and it has become an essential tool in various industries. But have you ever wondered when laser invented? It was one of the most important breakthroughs in modern technological history.

Laser (Light Amplification by Stimulated Emission of Radiation) was invented in 1960 by Theodore H. Maiman, an American physicist. It all began with the theory of maser (Microwave Amplification by Stimulated Emission of Radiation), which was proposed by Charles H. Townes and Arthur L. Schawlow at Bell Labs in 1954.

However, soon after, the scientists realized that if they could create a similar device that generated a different form of radiation, the possibilities would be endless. It lead them towards the direction of laser.

The invention of laser was not an easy process, and it took several years for scientists to achieve a breakthrough. Let's take a closer look at how Theodore H. Maiman invented the laser and the impact it has had on various industries.

The Theodore H. Maiman Era

Theodore H. Maiman was a physicist renowned for his work in laser technology. He completed his Ph.D. at Stanford University in 1957 and went on to work at the Hughes Research Laboratories in California. In 1960, after experimenting with various types of materials, Maiman successfully created the world's first laser.

However, it is worth noting that Maiman was not the only one working in this direction. Various scientists and researchers were working on creating a device that could generate laser-like radiation. Several other researchers were able to produce light, but they were not lasers because the light was emitted in all directions and failed to satisfy the requirements for stimulated emission.

The Working Mechanism of a Laser

As mentioned earlier, the working mechanism of a laser is based on the principle of stimulated emission. Laser works by producing a highly concentrated and narrow beam of light that is only one color or wavelength. It is done by exciting atoms or molecules within a medium, such as a crystal or a gas, to emit photons that match the incoming light in wavelength and direction.

The process results in a highly intense and coherent beam of light with specific properties, including the ability to travel over long distances without losing intensity or dispersing.

The Impact of Laser on Various Industries

Since its invention, laser has become an indispensable tool in several industries, including medicine, military, communication, and manufacturing, among others.


One of the earliest and most significant impacts of laser is on medicine. Laser technology is used in various surgical procedures, including cosmetic surgery and vision correction surgery. It is also used to remove tattoos, scars, and birthmarks. The precision of laser technology allows for minimal invasion and faster healing time.


Laser technology has been significant in military applications as well. It is used for long-range target identification, laser-guided weapons, and missile defense systems.


Laser technology has also revolutionized communication. It is used in fiber-optic communication systems, which transmit data over long distances at high speeds without any loss of information.


Laser is also widely utilized in manufacturing. It is used in cutting and engraving of various materials, including metals, plastics, and ceramics, among others.


Theodore H. Maiman's invention of the laser revolutionized technology in many ways. Laser has become an essential tool that has impacted various industries, including medicine, military, communication, and manufacturing, among others. Its precision and efficiency have opened up new opportunities and raised the bar for innovation. Today, laser technology continues to evolve, and its impact on industries and innovation is expected to continue in the coming years.
