One of my homemade baking soda lasers in action. I used a reaction between baking soda and vinegar to produce the CO2 gas necessary for lasing. The invisible laser beam is focused onto the surface of an ordinary rock. The resulting power density causes the rock to melt and burn. When I move the rock, the effects of the laser beam become increasingly dramatic. Occasional sparks are produced as the rock is moved through the beam path.
Because skill level varies from one individual to the next, as do resources in terms of time and money; my examples of laser construction should be viewed as guidelines only. Much of what I build is done using common hardware, and is based upon accumulated skill and knowledge from proceeding projects.
The construction or use/operation of any laser device can be hazardous. Laser beams can cause permanent blindness, and the electrical power supplies can be deadly.
