India's First Indigenous High-Precision Diode Laser Launched Under National Quantum Mission
Union Minister of State Dr Jitendra Singh launched India's first indigenous high-precision diode laser at ESTIC 2025 in Bharat Mandapam, New Delhi on November 3, 2025. The laser was developed by Prenishq Private Limited, an IIT-Delhi spin-off startup, with support from the National Quantum Mission (NQM).
The laser features ultra-narrow linewidth with a wide wavelength range from ultraviolet to near-infrared. It is critical for quantum communication applications including Quantum Key Distribution (QKD) networks, quantum computing, and cybersecurity enhancement. This marks a significant step in India's push for self-reliance in quantum technology infrastructure.
