Amaya Toman Nowadays, lasers are a fairly common part of our lives and the technologies that surround us every day. Its roots date back to the beginning of the last century, but the laser as a device was first patented only in 1960, and it is this event that we will recall in today's article. In the second part of today's historical summary, we will talk about the Pentium I processor from the Pentium company.

Patented Laser (1960)
On March 22, 1960, Arthur Leonard Schawlow and Charles Hard Townes were granted the first ever laser patent. The patent officially belonged to Bell Telephone Laboratories. The word Laser is an acronym for the term Light Amplification by Stimulated Emission of Radiation. Although the principle of the laser was already described in the first half of the last century by Albert Einstein himself, the first truly functional laser was built by the above-mentioned experts only in 1960. Four years later, Charles Townes was one of the three scientists who received the Nobel Prize for fundamental research in field of quantum electronics, which led to the construction of oscillators and amplifiers based on the principle of masers (emitting microwaves instead of light) and lasers.
Here Comes the Pentium (1993)
On March 22, 1993, Intel announced that it was beginning to distribute its new Pentium microprocessor. It was the first ever processor from Intel with this marking, which was originally intended to denote the fifth generation of Intel processors, but eventually became a brand with its own trademark. The clock frequency of the first Pentium was 60-233 MHz, four years later Intel introduced its Pentium II processor. The last processor in the Pentium series was the Pentium 2000 in November 4, followed by the Intel Pentium D.
