| Popis: | An improved passive self-injection locking (PSIL) method for the spectral control of dye and Ti:Al2O3 lasers using two-step pulse laser pumping is reported (theoretically, experimentally). By this pump technique, the typical unwanted free lasing which occurs in the non-selective cavity at high pump level is reduced by a few orders of magnitude compared with the standard PSIL application. This combined approach ensures high purity tunable emission at laser efficiency nearly equal to the maximum obtained in an optimized non-selective cavity and avoids optical damage problems. This makes the PSIL method competitive or preferable to other frequently used spectrally selective methods. Analysis and experimental check for two-wavelength lasers are included. |
