LASER PHOTONICS – UNDERSTANDING THE BASICS

-


“Laser” is an acronym for Light Amplification by Stimulated Emission of Radiation.

Photonics explores the characteristics and uses of photons, focusing on their role in information transfer. Practical applications include laser technologies for tasks such as cleaning, cutting, engraving, and marking in our daily lives.

The development from maser to laser marked a significant advancement in technology. Charles Hard Townes' work laid the foundation, leading to the creation of the first optical oscillator in 1957, and subsequently, the term "laser" emerged. The application for a US patent and its eventual granting in 1960 solidified the breakthrough in the field of optics and paved the way for diverse applications of lasers.

Let’s understand Laser through illustration with graphics;

LASER TECHNOLOGY FOR DIAMOND CUTTING PROCESS     The history of diamond processing and the development of laser technology indeed intersect at various points, leading to significant advancements in diamond cutting and various industries. Diamond processing has a long history, dating back centuries. Traditional diamond cutting involved labor-intensive methods, and it wasn't until the invention of the diamond saw in the 15th century that significant progress was made in shaping diamonds. However, these methods were limited in precision and speed. In the 20th century, the emergence of laser technology marked a turning point in diamond processing. Albert Einstein's work in the early 20th century, particularly his theoretical groundwork on stimulated emission of radiation, laid the foundation for the development of lasers. His concepts were essential in understanding the principles of how lasers function. In 1960, Theodore H. Maiman created the first functional laser at...
