In my presentation I will explain how lasers work, starting with the simple aspects including atoms, energy levels, and photons. I will then go into details about how I built my laser and different aspects that are important including a high voltage power supply, smooth electrodes, and an extremely fast discharge path. Also, my talk will include what a nitrogen laser looks like along with ways of determining that it actually lazes. Since this laser puts out pulses in the Ultra-violet it cannot be seen with the naked eye. The final part of my presentation will include firing the laser and using two different visual methods show that lasing action is occurring.
