Fortunately for scientists in the real world, the show also provided details of the type of laser(oxygen iodine laser) and its power(500kW). So what are you waiting for? =)
Normally one would just have to pour hot water into a pot of noodles and wait for two minutes for the noodles to absorb the water. The show, however, described "heating up" the pot. So it is assumed that cold (room temperature) water is put in the cup and heated by the laser to boiling point.
The water, however, did warm up by the meagerest amount.
