The technique of making tunable dye laser involves various technological challenges, including tailoring the properties of light according to the specific needs. Many practical applications require high output average power, good beam quality and, more importantly, spectral (wavelength and bandwidth) stability. Broadly tunable dye laser has created profound impact on various fields. Development of such tunable laser sources, catering to ever-demanding spectroscopic applications, is a very active field of research. Therefore, issues related to spectral stability of a narrow bandwidth high repetition rate dye laser are investigated. Succinct review on a complete dye laser system starting from gain medium characteristics, resonator, and excitation sources and other issues from microscopic to macroscopic levels associated with the high repetition rate are discussed. More specifically, it looks at the effects of high repetition rate excitation on the stability of the laser characteristics. For these purposes, novel diagnostic technique for large scale data acquisition, its presentation, and its precise measurements are formulated and effectively executed to explore the dye laser short/long-term spectral stability. These studies have brought out technologically advanced and highly stable high repetition rate and narrow bandwidth tunable dye laser suitable for its potential applications. A brief assessment of present state-of-art technological advancement in the field of other tunable laser sources is also presented.
