Description

technical field [0001] The invention relates to a laser amplifier, in particular to a semiconductor conical laser amplifying system under single-pass and double-pass composite modes. Background technique [0002] In the fields of cold atomic physics research and precision measurement, laser is an indispensable experimental resource and the main means of operation. A complete cold atom interferometer experiment often requires a variety of lasers with different frequencies and different powers to act on the atoms simultaneously or time-divisionally to achieve complex manipulation of the atomic groups. Please refer to the literature (Test of EquivalencePrinciple at 10 -8 Level by a Dual-Species Double-Diffraction RamanAtomInterferometer, Zhou Lin et al., Phys. Rev. Lett. Vol. 115, p. 013004, 2015). A complete interferometer experiment requires a variety of different lasers, such as cooling light, back pumping light, and Raman light. These lasers have different frequencies and...
