Abstract Title: W52 - Open Frame Helium Neon Laser
Abstract: The humble HeNe Laser is still important for education in Photonics. We demonstrate an open cavity training system with components like the HeNe tube with Brewster windows on sides, the two cavity mirrors and line tuning elements are placed onto the optical rail. The basic alignment is demonstrated and the beam diameter inside the cavity is measured to verify the nature of Gaussian beams. By means of a Littrow prism the line tuning is demonstrated. The power of the laser is determined by measuring the current of the provided photodiode. Cleaning of optical components is trained as well as the proper use of sensitive optical components.
