141 Light waves emitted with in the laser at wavelengths such as 6328,11,177 and 11,523 A 0 will occasionally be omitted parallel to the tube axis .Bouncing back and forth between the end mirrors, these waves will simulate emission of the same frequency from other excited neon atoms , and the initial wave with the stimulated wave will travel parallel to the axis. Most of the amplified radiation emerging from the ends of the He – Ne gas laser are in the near infrared region of the spectrum , between 10,000 and 35,000 A
