I think our love for lasers can be traced back to the numerous James Bond and other movies that feature over-exaggerated laser devices.
You see a laser on-screen that can supposedly slice the damsel in distress or a laser that can be used in some evil plot for world domination.
What's the first thing that comes to mind....
I want one of those!!!
Unfortunately, some movies do feature some lasers which are practically impossible to manufacture (regardless of money). However, there are affordable lasers which are possible to obtain, such as red and green diode lasers. In a lame attempt to make it just as powerful as the ones on TV and the big screen, we modify them.
Obviously, a modified green laser can't cut through a slab of 1m thick boron steel. However, it does make good eye candy.
