ABSTRACT:
A laser apparatus including first and second frequency sweeping laser devices, the sweep frequency range of each being different. The output laser beams of the first and second laser devices are multiplexed by a multiplexer. The output laser beam of the multiplexer is transmitted to a photodetector for detecting the difference in frequency between those of the first and second laser devices. A frequency monitor, coupled to the photodetector, provides a signal to a control circuit which causes the first and second laser devices to sequentially sweep their respective sweep frequency ranges.
