Injection locking of an optically pumped FIR laser
Abstract
The practical possibility of optically pumped far-infrared laser stabilization by injection of a highly stable synthesized signal into the laser is experimentally investigated. The injection locking takes place in a 350 kHz locking range and the two lasers used in the experiment work on the 432 micron line of HCOOH pumped by the 9R (20) line of a CO2 laser. Locking range versus injected power attenuation is plotted, and it is noted that the locking range can be increased by improving the coupling of the injected signal. Experimental results show that this method can be efficiently used in the frequency range up to one THz, for metrological purposes.
