Robbie, this starts really well and promises a lot, but then sort of peters out.
You have heaps of talent and flair, remember that the viewer also wants to learn some thing useful/find something out as well as be entertained.
Well done though :)

- Types of lasers
- Future predictions
In 1957, Charles Hard Townes and Arthur Leonard Schawlow, then at Bell Labs, began a serious study of the infrared laser.
As ideas were developed, infrared frequencies were abandoned with focus on visible light instead.
The concept was originally known as an "optical maser". Bell Labs filed a patent application for their proposed optical maser a year later.
Schawlow and Townes sent a manuscript of their theoretical calculations to Physical Review, which published their paper that year.
- Chemical lasers
- Excimer lasers
- Solid-state lasers
- Fibre-hosted lasers
- Fiber disk laser
- Semiconductor lasers
- Dye lasers
- Free electron lasers
- Nuclear reaction lasers
- Photonic Crystal lasers
Its said to be converted into highly dangerous weapons and also tools that would be used in everyday life.
