<h3>What is a helium-neon laser used for?</h3>
When compared to other gas lasers, helium xenon lasers are inexpensive and straightforward to operate. They have a long history of employment in numerous industries, including holography, biomedical engineering, metrology, spectrometry, optical disc reading, barcode scanning, and microscopy.
<h3>How does the helium-neon laser operate?</h3>
By energizing Neon molecules in the atmosphere, a He-Ne laser produces light. The Neon particles decay from a higher energy state to that of an ordinary state, producing the 632.8 nm optic light that the laser emits. For the given basic research, a comprehensive determination of quantum (state) is not necessary.
