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.

About This Site:
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. I disclaim any liability
associated with any information contained within this site, from any of the sites to which this
site links, or from any form of references contained within this site.

WARNING: Construction and operation of any laser device is hazardous.
Do not attempt to construct or operate a laser without adequate safeguards and safety practices.
Most lasers involve high voltages, toxic chemicals, high vacuum, laser radiation and other hazards.
The author specifically disclaims any and all liabilities associated with the construction and use of
such devices. Designs presented here are in the interests of providing information on operational
principles only and do not represent safe nor ANSI safety compliant designs.
