DeepLase makes fibre lasers and specialty optical fibres for industrial use
The IIT Delhi spinout designs optical fibres and laser systems for precision manufacturing, communications, sensing, healthcare instrumentation and quantum research.
Lasers cut and weld metal in factories across India, and most of the machines doing it are fibre lasers. The beam is generated inside a strand of glass rather than a gas tube or a crystal, which makes the design compact and efficient. Almost none of those machines are built here, and the reason sits deeper in the supply chain.
The fibre at the centre of the laser determines how the whole system performs. Specialty fibres of that kind are made by a small number of suppliers worldwide, and none of them is in India, so an Indian manufacturer building a laser starts by importing the part that matters most.
was set up in New Delhi to work on that layer. It was founded by Dr Deepak Jain, a faculty member at IIT Delhi. His research covers advanced optical fibre technologies and laser systems. The startup is incubated at the institute's Foundation for Innovation and Technology Transfer (FITT).
The company designs specialty optical fibres, builds fibre-laser platforms around them, and works on integrated photonics, where optical components are combined onto a single chip in the way electronic circuits are.
Specialty fibre is the most difficult element to crack. An ordinary telecom fibre carries a signal. A fibre built for a high-power laser has to do three things at once: carry the light without breaking down, keep the beam quality steady, and survive intense heat. Meeting all three means carefully designing the glass, the materials added to it, and the shape of its core, together as one system.
Building the fibre and the laser around it in the same company is unusual. Most laser makers buy their fibre in, which leaves them designing around a component somebody else has specified.
From the optical bench to the shop floor
The company is not chasing better raw performance, since laboratory laser systems already perform well enough. The problem is that they are built for a laboratory rather than the real world. They are hard to integrate into other equipment, sensitive to their surroundings, and struggle anywhere that vibrates, overheats or has to run without stopping.
DeepLase says it is engineering laser architectures for those conditions instead, designing for stability, energy efficiency and reliability at the system level rather than optimising a single specification. Jain has described the aim as combining optical fibre design, materials engineering and system reliability in platforms that stay practical in demanding industrial environments.
The applications the company lists run wide: precision industrial automation, optical communications, advanced sensing, healthcare instrumentation and quantum technologies. Those markets share a dependence on light sources that behave predictably, which is what a specialty fibre is engineered to deliver.
Quantum work is the most demanding of them. Experiments that manipulate individual photons need sources whose wavelength and intensity hold steady over long runs, and the equipment is largely imported.
Rs 6 crore, and a manufacturing build-out
The company raised Rs 6 crore in a seed round announced in March 2026, co-led by Mounttech Growth Fund's Kavachh and Yali Capital. Kavachh invests in defence and strategic technologies; Yali Capital backs deep technology, with a focus on semiconductors and hardware.
The funds will be utilised for engineering and manufacturing capacity, commercialising the products, and scaling deployments across the sectors the company has named. The funding release makes no defence claim for the products themselves.
The wider position DeepLase describes for itself is building photonics infrastructure in India rather than importing it. Specialty fibre and high-power laser supply chains sit largely outside the country, and the components that matter are difficult to source and slow to qualify. Its investors have framed the round as part of a shift towards deep-technology companies emerging from Indian academic laboratories.
The startup has not shared any customer, order or revenue figures publicly.
