چکیده
|
A q-switched thulium-doped fiber laser (tdfl) operating at approximately 2 �m wavelength is successfully generated by using four different saturable absorbers (sas) which are nitrogen-doped graphene in pva (ng:pva),nitrogen-doped graphene in peo (ng:peo),single-walled carbon nanotube in pva (swcnt:pva),and high pressure carbon monoxide carbon nanotube in pva (cnthipco:pva). the sas integrated in the cavity were able to provide the real saturable absorption in modulating the intra-cavity losses. swcnt gives the best results with the highest repetition rate and lowest pulse width of 57.45 khz and 1.958 nj correspondingly as compared to the other three sas. � 2016 penerbit utm press. all rights reserved.
