چکیده انگلیسی
We proposed an injection-seeded Q-switched Ho: YLF laser by a tunable single-longitudinal-mode Tm, Ho: YLF laser. The tunable single-longitudinal-mode seed laser was achieved by inserting two Fabry-Perot (F-P) etalons in the Tm, Ho: YLF laser resonant cavity and changing the cavity length through a piezoelectric transducer (PZT). The wavelength of single-longitudinal-mode Tm, Ho: YLF laser could be tuned from 2050.962â¯nm to 2051.000â¯nm finely. The single-longitudinal-mode output power of 76â¯mW from Tm, Ho: YLF seed laser was achieved at the CO2 absorption peak of 2050.967â¯nm. Single-frequency Q-switched Ho: YLF laser was achieved by injection seeding. The output energy of single-frequency Q-switched Ho: YLF pulse was 4.4â¯mJ, with a pulse width of 65â¯ns and a repetition frequency of 100â¯Hz. The beam quality factor M2 of Ho: YLF laser was 1.07, nearly diffraction limit. The full width at half maximum (FWHM) of single-frequency pulse Ho: YLF laser measured by a heterodyne technique was about 4.1â¯MHz with the simultaneously recorded pulse width of 132â¯ns.
