Narrow-linewidth, single-frequency semiconductor laser with a phase-conjugate external-cavity mirror
Technical Report
·
OSTI ID:6410967
Spectral characteristics of an external-cavity semiconductor laser, which uses a phase-conjugate mirror for its external reflection were measured. This device has significant advantages over the conventional external-cavity system owing to the self-aligning nature of the phase-conjugate mirror. The fiber delay line self-heterodyne technique is used to measure the fundamental linewidth for single-mode operation of this device. It shows the linewidth to be at least as narrow as the instrumental resolution of 100 kHz.
