Karsten Berr,Sebastian Feldhuseniled descriptions of various maser sources in the following chapters. The discussion here is necessarily brief, and concentrates on concepts and processes with the most relevance to maser operation. This astronomical background material can be supplemented by the following references: the book . by

This molecule still provides the largest variety of astronomical sources displaying maser activity. Strong OH maser emission is observed in both star-forming regions and late-type stars. Weak maser effects are prevalent in l

Among those, methanol (CH.OH) and ammonia (NH.) have generated the most activity and show the promise that they soon will join the three “classical” masers OH, H.O and SiO as equally important. This chapter summarizes the current status of maser studies of t

In such cases maser radiation provides a general astronomical tool, employed in the analysis of properties altogether unrelated to maser action per se. This final chapter describes some of t
