Seems too "explosive" to be just infrared laser. The explosive response can only happen if the metal is instantaneously vaporized, like an armor-piercing round. Additionally, they note it will only be ready for use in the early 2020s. Seems like a very long time if they already have a working prototype - especially if short-range protection is so critical and an urgent need of the navy.
PS: after watching again, it looks like they may be firing a laser at an explosive on the target
