Indigenously-built high-precision diode laser – NQM-supported startup demonstrates India’s first indigenous high-precision diode laser for quantum-encrypted communication and computing.
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.
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 the financial and banking industry to provide quantum-safe transactions, protecting sensitive client information and critical business data. These precision lasers will also help photonic quantum computers solve previously incomputable problems, such as drug discovery and chemical process analysis, benefiting both society and the environment.
The integrated driver electronics ensure stable output power and temperature-controlled operation across a range of varying environmental conditions. The small form factor of the laser system offers high efficiency with low power consumption. Its free-space and optional fibre-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 their 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 position India at the forefront of laser technology and quantum innovation. The innovation aligns with the vision of the Hon’ble Prime Minister, Shri Narendra Modi, who envisions India as a leader in manufacturing quantum technology products.
The innovation was made possible thanks to the support of several organisations, including DST-Nidhi Prayas, the National Mission on Interdisciplinary Cyber-Physical Systems (NMICPS), the National Quantum Mission (NQM), the I-HUB Quantum Technology Foundation, IISER Pune, the Foundation for Innovation and Technology Transfer (FITT), IIT Delhi, the BITS BioCyTiH Foundation, and TBI-KIET.
