Featuring Experimental Lasers



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.

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.

Chris Hill

October 30, 1971
March 30, 2021

Chris was a skilled craftsman, an adventurous experimenter and an amateur scientist who enjoyed making lasers and model airplanes. Like myself, Chris enjoyed designing and building things from basic materials. Chris was a perfectionist - he never did anything halfway. The devices he built looked as though they had been manufactured commercially.

To me, Chris was a dear friend. There is a place in my life that Chris occupied, and no one else can fill that place. Though he could design and build anything, Chris had a heart that was as big as his hands - he was a caring soul who could understand personal matters and relate to others during difficult times.

Chris was undoubtedly many things to many people, but most of all he was a dedicated husband and loving father who treasured his family!
