The KALI (Kilo Ampere Linear Injector) is a linear electron accelerator being developed in India, by the Defence Research Development Organization (DRDO) and the Bhabha Atomic Research Centre (BARC).
The KALI is not a laser weapon as commonly believed. It emits powerful pulses of electrons (Relativistic Electron Beams- REB). Other components in the machine down the line convert the electron energy into EM Radiation, which can be adjusted to x-ray (as Flash X-Rays) or microwave (High Power Microwave) frequencies.
This has fueled hopes that the KALI could, one day be used in a High-Power Microwave gun, which could destroy incoming missiles and aircraft through soft-kill (destroying the electronic circuitry on the missile). However, weaponising such a system has many obstacles to overcome.
As a Weapon
The KALI's potential for a military role as a beam weapon has made it, in the eyes of the people, "India's Star Wars". However, weaponisation of the KALI will take some time. The system is still under development, and efforts are being made to make it more compact, as well as improve its recharge time, which, at the present, makes it only a single use system.
There are also issues of creating a complete system, which would require development of many more components. There have also been reports of placing the weaponized KALI in an Il-76 aircraft as an airborne defence system. There is also speculation of using the KALI as an Anti-satellite weapon and as a space-based weapon system, although it is unlikely that they would be implemented, given India's stance on those issues.
If weaponized, it is quite likely that KALI would be integrated into India's Ballistic Missile Defense program.

As of now, there is no proof that India is weaponizing the KALI. There is a possibility that it is developed as a secret project.
