| Zusammenfassung: | An exocoel type electric light tunable laser provided in the utility model employs an electric light tunable filter, which is a liquid crystal Fabry-Perot cavity with the cavity length very short, the filter is guaranteed that only one mode fixing the Fabry-Perot cavity is selected in a period interval, a broadband membrane filters the periodical multiple peaks generated in fixing the Fabry-Perot cavity, and only reflects the wavelength of one peak to an optical resonator, thereby one peak of the optical resonator longitudinal mode is adjusted to the main peak of electric light tunable filter through the electric light tunable phase compensator, laser can be output in a single mode, and the output stability and reliability of laser can be enhanced. |
