New Delhi: India’s first indigenous high precision and compact diode laser, developed by a startup supported by the National Quantum Mission, Prenishq Pvt Ltd, a spin-off from IIT Delhi, marks a significant leap in the nation’s capability for all emerging quantum technologies. It paves the path towards quantum encrypted communication and computing.
The high-performance, precision-engineered laser is designed for quantum research, higher education, and advanced scientific applications. Delivering exceptional beam quality, superior stability, and long-term reliability, it integrates seamlessly with a wide range of scientific and industrial systems.
A formal launch of the laser was made on November 3, 2025 at the Emerging Science, Technology and Innovation Conclave (ESTIC 2025) by Dr Jitendra Singh, Hon’ble Union minister for Science and Technology. Prof Ajay K Sood, Principal Scientific Adviser to the Government of India, Dr Ajai Chowdhry, Chairman, National Quantum Mission (NQM), Prof Abhay Karandikar, Secretary, Department of Science and Technology and other officials were present on this occasion.
The simplicity of operation covering a wide range of wavelengths from ultraviolet to near infrared makes these lasers a true enabler of quantum technologies. In particular, the laser will open the door to financial and banking industry to provide quantum safe transaction, protecting sensitive client information and critical business data. These precision lasers will also help the photonic quantum computers to solve previously uncomputable problems such as drug discovery and chemical process analysis to benefit both society and environment.
The integrated driver electronics ensure stable output power and temperature-controlled operation across varying environmental conditions. Small form factor of the laser system offers high efficiency with low power consumption. It’s free-space and optional fiber coupled optical output together with plug-and-play configuration make it suitable for integration into both educational and research laboratories.
By enabling precise control of wavelength and power stability, Prenishq’s high precision diode lasers support a broad range of quantum optical experiments and quantum research, reinforcing India’s capability in developing indigenous quantum-grade instrumentation.
These lasers stand out for its low cost of ownership, ease of installation, minimal maintenance, compact design with less weight, and assured availability to promise. Combining performance, efficiency, and accessibility, Prenishq’s lasers positions India at the forefront of laser technology and quantum innovation. The innovation aligns with the vision of Prime Minister, Narendra Modi, who envisions India as a prominent leader in manufacturing quantum technology products.
The innovation was made possible with the support from DST-Nidhi Prayas, National Mission on Interdisciplinary Cyber Physical Systems (NMICPS) and National Quantum Mission (NQM), I-HUB Quantum Technology Foundation, IISER Pune, Foundation for Innovation and Technology Transfer (FITT), IIT Delhi, BITS BioCyTiH Foundation and TBI-KIET.
