12.1 Introduction

Since the early days of organic tunable lasers, there has been interest in solid-state tunable organic dye lasers [1,2]. Early interest in the electrical excitation of these molecular species has also been documented in the literature [3,4].

For many years, interest in solid-state tunable organic dye lasers was sporadic, until in the early 1990s, when advances in solid-state organic dye gain media reenergized activity in the field. For a generalized perspective on solid-state organic dye lasers, the reader can consult Chapters 3 and 4.

Despite the enormous success of broadly tunable optically pumped lasers, as evidenced in the various chapters on the ...
