[19a-431B-2] Higher output power of the laser which keep the beam in single longitudinal and transverse mode oscillation
Keywords:LASER, single mode oscillation, injection locking
In order to increase the power of the laser, the beam diameter inside the resonator must become larger to reduce the light intensity per unit area. However, if the resonator is simply designed to be large the beam diameter inside, it will oscillate to the multimode and a hot spot will be formed, which will lead to a vicious circle that it will be more easily damaged. In this presentation, I will report on the newly designed resonator which keeping the beam in the single longitudinal and lateral mode oscillation and the performance obtained actually with the laser resonator.
