| titleOfInvention | Dual-wavelength pumping thulium-doped laser based on GSA and ESA |
| abstract | The invention discloses a dual-wavelength pump thulium-doped laser based on a GSA (generalized Gaussian) and an ESA (extreme-mode optical amplifier), which consists of a GSA pump source, an ESA pump source, a pump light beam combiner, an input mirror, a thulium-doped laser medium and an output mirror. GSA is ground state absorption corresponding to thulium-doped laser medium 3 H 6 → 3 H 4 Transition, ESA is excited state absorption, corresponding to 3 F 4 → 3 H 4 Is detected. Pumping by GSA pump source based on 3 H 6 → 3 H 4 The Tm of the thulium-doped laser medium is obtained by the ground state absorption caused by the transition 3+ Ion pumping to 3 H 4 And energy level, and realizing the first layout of the population of the energy level. Meanwhile, the cross relaxation process between thulium ions can further realize the metastable state 3 F 4 Population topology of energy levels. Pumped by ESA pump source, using 3 F 4 → 3 H 4 Excited state absorption caused by the transition will 3 F 4 Precise pumping of the accumulated particle number on the energy level to 3 H 4 Energy level, realization 3 H 4 A second placement of energy level population. The scheme of the invention can effectively improve the pumping of the thulium-doped laser medium by GSA and ESA dual-wavelength 3 H 4 → 3 H 5 The upper energy level particle number transition layout improves the output power of the laser with the wave band of 2.3-2.5 μm. |
