| description | Izum spada na področje laserskih, natančneje na področje konstrukcijskih detajlov laserskih naprav ter laserskih naprav za kontrolo intenzitete, frekvence, dolžine, polarizacije ali smeri izsevanih žarkov. Pričujoči izum je izboljšan vlakenski laser s preklopom ojačenja, ki omogoča spreminjanje ponavljalne frekvence v velikem obsegu in pri tem ohranja konstantno vršno moč ter trajanje izhodnih laserskih pulzov. Bistvo laserja po izumu je črpalni sistem, katerega izhod je sklopljen v oziroma navarjen naoscilator, in črpa tako oscilator kot ojačevalnik. Črpalni sistem vključuje primarni in sekundarni črpalni modul s po vsaj enim črpalnim diodnim laserjem, pri čemer primarni modul proizvaja kratke črpalne pulze ter pri čemer primarni in sekundarni modul delujeta pri različnih vršnih močeh. Moč, ki jo proizvede sekundarni modul, se neposredno porabi za zmanjšanje učinka relaksacije aktivne snovi preko spontane emisije med laserskimi pulzi, kar omogoča generiranje kratkih laserskih pulzov na zahtevo skonstantnimi parametri.
The invention belongs to the field of lasers, more precisely to the field of constructional details of laser devices and laser devices for controlling intensity, frequency, length, polarization or direction of emitted rays. The present invention is an improved gain switched fiber laser, which enables changes of repetition frequency in a large range and which, at the same time, maintains a constant peak power and duration of generated laser pulses. The essence of the laser according to the invention is the pump system which is coupled to an oscillator and pumps the oscillator as well as the amplifier. The pump system comprises a primary and a secondary pump module, each at least with one pump laser diode, wherein the primary module generates short pump pulses and wherein the primary and secondary pump module operate at different peak powers. The power generated by the secondary module can be directly used to decrease the effect of active medium relaxation via spontaneous emission in-between laser pulses, which enables generation of short laser pulses on demand having constant parameters. |
