Abstract
The embodiment of the invention provides a laser generator and a method for generating laser. The laser generator comprises a narrow pulse output module and a semiconductor laser module which are connected in sequence, wherein the narrow pulse output module is configured to expand a trigger signal into a first pulse signal and a second pulse signal when the trigger signal is received; wherein the first pulse signal and the second pulse signal are opposite in phase; the narrow pulse output module is further configured to perform delay processing on the first pulse signal relative to the second pulse signal, and perform logical operation on the second pulse signal and the delayed first pulse signal to obtain a target narrow pulse signal. The target narrow pulse signal is output to the semiconductor laser module; and the semiconductor laser module is configured to output narrow pulse laser according to the received target narrow pulse signal.
Description
technical field [0001] The present disclosure relates to the field of laser technology, in particular to a laser generator and a method for generating laser. Background technique [0002] A narrow-pulse laser source with a high repetition rate is a necessary device for quantum communication. At present, there are various commercial laser products on the market. The operating frequency of these lasers is up to 100MHz, and the FWHM is less than 40ps; or the operating frequency is up to 1.25GHz, and the FWHM is less than 50ps. However, with the continuous development and upgrading of quantum communication technology, higher requirements are put forward for the operating frequency of lasers. The existing lasers obviously have inconvenience and defects in actual use, and it is necessary to improve them. Contents of the invention [0003] According to the first aspect of an embodiment of the present disclosure, a laser generator is provided, the laser generator includes: a narr...
