Frequency Shanduko
KTP yakatanga kuunzwa seNLO crystal yeNd doped laser masisitimu ane yakanyanya kutendeuka kunyatsoita. Pasi pemamwe mamiriro ezvinhu, kutendeuka kwekushanda kwakashumwa ku80%, iyo inosiya mamwe makristasi eNLO kure kumashure.
Munguva pfupi yapfuura, nekuvandudzwa kwemalaser diode, KTP inoshandiswa zvakanyanya seSHG zvishandiso mu diode pumped Nd: YVO4 yakasimba laser masisitimu kuburitsa green laser, uye zvakare kuita kuti laser system inyatso compact.
KTP YeOPA, OPO Zvikumbiro
Pamusoro pekushandisa kwayo kwakakura sechinhu chinopeta kaviri mudziyo muNd-doped laser masisitimu eGreen/Red kubuda, KTP zvakare imwe yemakristasi akanyanya kukosha mune parametric sosi ye tunable kubuda kubva kunoonekwa (600nm) kusvika pakati-IR (4500nm) nekuda kwekuzivikanwa kwemapombi ayo masosi, iyo yakakosha uye yechipiri harmonic yeNd: YAG kana Nd: YLF lasers.
Chimwe chezvishandiso zvinonyanya kukosha ndeye non-critical phase-matched (NCPM) KTP OPO/OPA inopombwa neainable lasers kuti iwane yakanyanya kupinduka inoshanda.KTP OPO inoguma yakagadzikana inoenderera inobuda yefemto-yechipiri pulse ye108 Hz yekudzokorora mwero. uye milli-watt avhareji masimba emagetsi mune ese masaini uye asina kuita zvinobuda.
Yakaputirwa neNd-doped lasers, KTP OPO yakawana pamusoro pe66% shanduko inoshanda yekudzika-shanduko kubva pa1060nm kuenda ku2120nm.
Electro-Optical Modulators
KTP crystal inogona kushandiswa se electro-optical modulators. Kuti uwane rumwe ruzivo, ndapota taura nevatengesi vedu mainjiniya.
