The patent describes a non-cavity laser having the gain-possessing-medium outside of a Fabry-Perot cavity. A low power laser having a Fabry-Perot cavity is used to provide the driving signal for a high power non-cavity laser. The electric field of the active Fabry-Perot cavity extends beyond the cavity to stimulate emission in the active medium of the high power laser and synchronize the output thereof with the cavity oscillation. Due to the synchronization between the output laser and the control laser, a detector that measures a low percentage of the light frequency of the control laser is readily calibrated to indicate output power.
