MAXIMUM GAIN FOR FORWARD AND BACKWARD WAVE OPTICAL MASER AMPLIFIERS,
Abstract
An analysis was made of the mechanism of amplifi cation in a device consisting of three media. The first medium is considered to be air, the second medium to be a crystal having a specific dielectric constant and distributed negative conductivity of constant value, and the third medium air. The equations for power gain in transmission and reflecti-re derived in a general manner. Following this, the condition on the length of the active region for maximum power gain in both forward and reflected modes of operation is approximated as well as the magni tude of gain. When the development is applied to the ruby optical maser, the length producing maximum gain is found to be the same for both the reflection and transmission type amplifier. Furthermore, as the length of the crystal is increased, oscillations are predicted at a single optimum value of the product of the negative at tenuation constant and length. (Author)
