Brandnew' Volume-Holographic-Grating- (VHG) Stabilized Lasers yog laser diodes uas siv cov lus tawm tswv yim los ntawm lub ntim holographic grating los muab nqaim-linewidth, ib zaug ua haujlwm. Qhov no tso cai rau lub laser kom ua tiav 15 MHz raug linewidths nrog ib qho zoo heev sab hom kev sib piv (40 dB raug). Cov ntaub ntawv ntau ntxiv ntawm qhov ntsuas kub ruaj khov tuaj yeem pom ntawm daim ntawv teev cov ntaub ntawv tus kheej rau txhua lub laser diode.
Cov VHG-stabilized lasers no nyob rau hauv ib tug compact 14-pin hom 1 pob npauj npaim, ua kom muaj kev sib raug zoo nrog txhua tus qauv 14-pin laser diode mount. Cov pob npauj npaim muaj xws li kev sib xyaw ua ke hauv kev sib cais, lub tshuab cua txias (TEC), thermistor, saib photodiode, thiab ib hom tso zis fiber ntau nrog FC / APC txuas. Cov kev sib cais sab hauv thiab FC / APC connector muab kev tiv thaiv kev cuam tshuam rov qab uas tuaj yeem txo qhov kev ua haujlwm ntawm laser. Peb kuj muab VHG-stabilized TO tuaj yeem pigtail ntawm 785 nm.
Thaum lub nruab nrab wavelength tau teev tseg rau lub laser diodes hauv qab no, qhov no tsuas yog tus lej raug. Qhov nruab nrab wavelength ntawm ib chav tsev sib txawv los ntawm kev khiav mus rau ntau lawm, yog li lub diode koj tau txais yuav tsis ua haujlwm ntawm qhov nruab nrab wavelength.
Cov VHG lasers no tau sib xws nrog Brandnew' kab ntawm laser diode tsav tsheb thiab cov tswj kub. Txhawm rau kom ua tiav txoj kab dav dav, peb pom zoo kom siv tus tsav tsheb uas tsis tshua muaj suab nrov tam sim no, xws li peb cov LDC series tsav tsheb.
Laser diodes yog rhiab heev rau electrostatic shock. Thov ua tib zoo ceev faj thaum tuav lub cuab yeej, xws li siv ESD lub dab teg.
Brandnew kuj tseem muab cov lus qhia pigtailed faib tawm (DFB) ib zaus laser thiab kab noj hniav sab nraud thiab faib bragg reflector (DBR) npauj npaim-pob ib zaus lasers. Lub DFB lasers muab cov kab dav zoo sib xws rau VHG-stabilized lasers, tab sis muab kev hloov pauv tsis pub dawb ntawm ob peb nanometers thaum tswj kev ua haujlwm ib zaug. Cov npauj npaim ntim sab nraud cov kab noj hniav lasers muab txoj kab dav dav thiab ntau qhov chaw nruab nrab qhov kev xaiv ntau dua li peb cov VHG-stabilized lasers. Peb DBR ib leeg-frequency lasers muab ib qho zoo sib xws linewidth rau VHG-stabilized lasers, tab sis muaj qhov kub thiab txias- thiab tam sim no-tunable nruab nrab wavelength.
Fiber Care
Peb pom zoo kom ntxuav cov fiber ntau txuas ntawm lub pob pigtail ua ntej txhua qhov kev siv yog tias muaj qee lub caij nyoog uas cov plua plav lossis lwm yam kab mob tuaj yeem tso rau ntawm qhov chaw. Lub laser siv nyob rau hauv nruab nrab ntawm lub taub hau fiber ntau yuav ua tau siab heev thiab tej zaum yuav kub hnyiab tau ntawm cov fiber ntau yog hais tias muaj kab mob. Thaum cov connectors ntawm cov pigtailed laser diodes raug ntxuav thiab capped ua ntej shipping, peb tsis tuaj yeem lav tias lawv yuav nyob twj ywm tsis muaj kab mob tom qab lawv raug tshem tawm ntawm lub pob. Peb kuj pom zoo tias lub laser raug muab tua thaum txuas lossis txiav lub cuab yeej los ntawm lwm cov fibers.
