Comparison of standing wave and traveling wave resonators for an FIR laser
Abstract
The output powers of various linear and folded configurations of standing wave and traveling wave ring resonators for a FIR laser are compared. Output powers were measured for a linear standing wave laser and a ring laser of the same gain length and mode size, and for a folded standing wave laser and a figure-eight ring laser of the same gain length and mode size. The standing wave FIR lasers are found to be more efficient than the traveling wave ring lasers, a fact attributed to the higher average intensity in a standing wave resonator. Exceptionally high gain was obtained in the doubly folded standing wave laser, amounting to an output power of 100 mW for the 70.5-micron line of CH3OH at 22 W of pump power.
