Cov qoob loo thiab cov kabmob sab hauv yog ob npaug nd: Lasers siv cov zoo nkauj KTP nonlinear Crystal tau ua dua li cov xim ntsuab laser ntau rau ntau R &D, kev kho mob, khoom siv, thiab kev lag luam. Los ntawm kev siv cov kab noj hniav ntxiv KTP SHG, kev hloov dua siab tshaj ntawm 80% thiab 700 mg fais fab ntsuab tau muab nrog 900 MG txhaj-seeded Q-hloov Nd: YAG laser.
OPG, OPA, thiab OPO

Raws li tus OPO crystal pumped los ntawm kev siv thiab qhov sib haum ntawm Nd: YAG lossis Nd: YLF laser, kev siab zoo purity KTP nonlinear Crystal plays lub luag haujlwm tseem ceeb hauv kev ntsuas qhov muag kom pom tseeb ntawm pom (0.6 um) mus rau ib nrab IR ( 4.5 um). Lub NCPM OPO /OPA nrog cov X-cut KTP pumped los ntawm 1064nm yog qhov tseem ceeb tshaj li qhov teeb liab tawm ntawm qhov sib tw @ 1.57 um yog qhov muag zoo. NCPM KTP OPO /OPA pumped los ntawm qhov muag lasers xws li Ti: Sapphire, Alexandrite, thiab Cr: LiSrAlF6 kuj tau tshaj tawm txog kev ua haujlwm siab ntawm 45%.
