Light Beamer | Cost
The estimated cost of the laser array is based on extrapolation from the past two decades, and the prospects of mass production to reduce the associated cost.
Laser amplifier costs declined exponentially between 1990 and 2015, halving approximately every 1.5 years (18 months). If this this trend were to continue, it would bring the construction cost a large beamer orders of magnitude lower within the next decades.
