MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202611053240 A) filed by Poornima University; and Dr. Sharbari Deb, Jaipur, Rajasthan, on April 27, for 'lithium niobate crystal based electro-optically tunable ultrashort pulse shaping system for precision laser-assisted neurosurgery.'
Inventor(s) include Dr. Sharbari Deb.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses an electro-optically tunable ultrashort pulse shaping system configured as an integrated device for precision laser-assisted neurosurgical applications. The system comprises an ultrafast laser source, a beam conditioning unit, and a Lithium Niobate crystal-based electro-optic modulation arrangement coupled with a programmable voltage control unit. By applying controlled electric fields across the crystal, the system induces refractive index variations that enable dynamic modulation of pulse duration, phase, chirp, and peak intensity in real time. A pulse shaping processor executes a control technique to generate adaptive voltage waveforms based on desired pulse characteristics and feedback from tissue interaction. The shaped pulses are delivered through a beam delivery unit integrated with a neurosurgical probe to achieve highly localized and controlled energy deposition. The invention enables enhanced surgical precision, reduced thermal damage, and improved safety, thereby advancing minimally invasive neurosurgical procedures through real-time adaptive laser pulse control."
