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.

∙ 12y agopopulation inversion is the fundamental requirement to produce laser.
laser has following basic components:
1.gain medium
2.RF energy
3.high reflector mirror
4.output coupler
principle: when energy is given to gain medium , electrons / particles acquired this energy and they excited from lower energy state to higher energy state.
when no of paticles / electrons are more in higher state than lower state, population inversion achived. light is amplified by itself and laser is produced.

Why did Charles Hard Townes win The Nobel Prize in Physics in 1964?
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.
Who was the inventor of the laser?
Albert Einstein laid the foundation for the laser in 1917. The principle was found by H.Charles Townes. And Maiman found it in1960.
What are lasers used for?
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.
Who in invented the first laser?
American physicist Theodore Maiman constructed the first working laser in 1960.But research started in 1958
What are semiconductor diode laser describe with energy band diagram the construction and working of a semiconductor diode laser?
construction and working of semiconductor laser
What are the applications of junction lasers?
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.
