A New Method For Studying Modal Behavior And Temperature Tuning Of GaAs Lasers
The wavelength shift of a single mode of a pulsed, room-temperature GaAs laser was studied using the energy separation of the two hyperfine levels of the 62S 1 2 state of cesium to define a fixed-wavelength interval. A line-shift coefficient of 10-3 Å A-2 μs-1 for a single mode was measured. The predominant physical mechanism for the wavelength shift of a single mode appears to be the temperature dependence of the index of refraction of the laser material. © 1972.
