Narrow-bandwidth operation and improved beam quality of a semiconductor broad area laser in an improved variable-length external cavity

Coons, Ryan William

Abstract Details

2006, Master of Science, Miami University, Physics.
We have devised an improved collimation system for a variable-length Littman-Metcalf external cavity diode laser (ECDL), which greatly improves the quality of a broad-area laser (BAL). We expand on previous work by determining the spectral bandwidth, modal linewidths, and M2 beam quality factor of the ECDL. We have found that the improvement of beam quality is critical to spectral narrowing, and that a BAL will behave in the same way as any other laser would in an external cavity. The beam profiling techniques used to determine the M2 beam quality factor are discussed, along with other supplemental techniques to further enhance spectral narrowing.
