Characteristics of Thin-Film Energy-Transfer Dye Laser with DFB Oscillator-Amplifier System.

The operation of many thin-film ETDL's covering a wide wavelength range from near UV to near infrared has been reported. However, the spectral narrowing and tuning of these solid dye lasers are required inevitably for several applications. Therefore, to obtain this operation, the oscillator with a dynamic distributed feedback (DFB) and the optical amplifier were constructed simply on the thin-film ETDL waveguide. As a result, the tunable laser emission with narrow spectrum and its amplification were obtained easily over both gain bands of donor and acceptor dye. Thus, this system is available as a compact solid dye laser with wide tuning range. [ABSTRACT FROM AUTHOR]
