The Bhabha Atomic Research Centre (BARC), Bombay (now Mumbai), Maharashtra, successfully developed a semiconductor laser, making India one of the early countries to achieve this technological breakthrough.

Pioneering Work: The development of a semiconductor diode laser at BARC was a significant milestone in India’s laser research and optoelectronics.

Technology: Semiconductor lasers (also called laser diodes) use a p-n junction to produce coherent light through electroluminescence.

Applications: These lasers later became crucial for fiber-optic communication, medical applications, defense, and industrial uses.

It demonstrated India’s early advancements in laser physics, despite limited resources.

The breakthrough contributed to the growth of optoelectronics and photonics research in India.

It laid the foundation for later developments in laser-based defense systems, medical diagnostics, and fiber-optic networks.
