This book covers the most important results of studying liquid crystal microlasers for the last decade although the pioneering works on this type lasers have been made much earlier (for the history see Chapter 1). In fact, it is the first book on the subject. The main part of the book deals with low-threshold distributed feedback lasers on dye-doped cholesteric liquid crystals. These are helical materials that possess intrinsic periodicity and manifest optical ...
