NQM supported startup demonstrates India’s first indigenous high precision diode laser for quantum encrypted communication and computing

India has unveiled its first indigenous high precision compact diode laser, developed by Prenishq Pvt Ltd, an Indian Institute of Technology (IIT) Delhi spin-off supported by the National Quantum Mission. Launched at ESTIC 2025 by Union Minister of Science & Technology, Dr Jitendra Singh, the innovation marks a major advancement in India’s ability to build critical hardware for quantum communication, quantum-safe financial systems, and photonic quantum computing. Designed for research and higher education, the laser delivers high beam quality, long-term stability, and reliable performance across ultraviolet to near-infrared wavelengths, enabling seamless integration into scientific and industrial systems.
With integrated driver electronics, temperature control, low power consumption, and a small form factor, the system ensures efficient, stable operation in varied environments. Its free-space and optional fibre-coupled output, combined with plug-and-play usability, makes it suitable for classrooms, research labs, and industry. Positioned as an affordable, low-maintenance, and accessible quantum-grade instrument, the laser supports experiments requiring precise wavelength and power control. Backed by initiatives under DST-NIDHI PRAYAS, NMICPS, and the National Quantum Mission, the development aligns with the Prime Minister’s vision to make India a global leader in quantum technologies and strengthens the country’s indigenous quantum manufacturing ecosystem.
