the junction lasers principle is like a normal laser but a specific junction will activate it. This is good because if you are away from the where the laser is then you can activate it without being there.
Albert Einstein laid the foundation for the laser in 1917. The principle was found by H.Charles Townes. And Maiman found it in1960.
A laser works by emitting a concentrated beam of light through a process called stimulated emission, where photons are amplified and aligned to create a powerful and focused beam of light.
Theodore Maiman invented the first working laser on May 16, 1960. His invention marked a major breakthrough in the development of laser technology.
When working with a visible laser, it is important to wear appropriate eye protection to prevent eye damage. Additionally, ensure that the laser is properly secured and avoid pointing it at reflective surfaces or people. Follow all safety guidelines provided by the manufacturer and never look directly into the laser beam.
The Nobel Prize in Physics 1964 was divided, one half awarded to Charles Hard Townes for fundamental work in the field of quantum electronics, which has led to the construction of oscillators and amplifiers based on the maser-laser principle,the other half jointly to Nicolay Gennadiyevich Basov and Aleksandr Mikhailovich Prokhorov for fundamental work in the field of quantum electronics, which has led to the construction of oscillators and amplifiers based on the maser-laser principle.
construction and working of semiconductor laser
Applications of junction lasers are in terms of laser output beams as information carriers. Since this output beam needed to be modulated in terms of intensity, the junction laser is handy. The junction laser supplies regulated current.

A laser rangefinder uses a laser to determine the distance to an object. The principle used is the time of flight principle based on the speed of light.

it working of
what is principle work of filter when white light incident on it and laser incident too
CD-ROM works on the principle of the LASER and it is a major application of the LASER
For laser construction...
It would so cool!
Well the principle of stimulated emission was discovered by Albert Einstein. But first laser was fabricated by Theodore Mainman
