The N₂ laser-pumped dye laser is an important coherent light source used very widely in research applications of optical properties of various objects. However, it is difficult to obtain highly efficient laser operation in the near infrared range. This paper considers the operation and development of an energy transfer dye laser (ETDL) and the cascade ETDL operation in the near infrared range with the aim of improving the efficiency of the N₂ laser-pumped infrared dye laser. As a result, Nile-Blue-HITC ETDL and Nile-Blue- Cryptocyanine ETDL operating in the range of 700 nm - 900 nm have been realized. Furthermore, in the ternary dye mixture system with addition of Rhodamine-B to these dye mixtures, the cascade ETDL operations also occur efficiently. the high efficiency of the N₂ laser-pumped near infrared dye lasers has been realized by means of these ETDLs, and a wide tuning range laser operation has been obtained.
