Hauj lwm lawm
LiNbO3 siv lead ualug siv doublers zaus rau wavelength > 1 hli thiab kho qhov muag parametric oscillators (OPOs) pumped nyob 1064 nm li no quasi-phase-matched (QPM) pab kiag li lawm. Vim nws loj Electro-Optic (E-O) thiab coefficients Acousto-Optic (A-O), LiNbO3 siv lead ua yog qhov kheev siv khoom rau Pockel hlwb, Q-keyboards thiab theem modulators, waveguide substrate, thiab nto acoustic yoj tes wafers (kaw), thiab lwm yam.

Ib tug ntawm cov nonlinear muaju feem ntau yam, lithium niobate muaj ntau hom kev siv, xws li:
Kho qhov muag tes taws los piav thiab Q-switching.Tsaug cov loj electro-optic coefficients, lithium niobate yog zoo suited los kho qhov muag tes taws los piav thiab Q-switching txog infrared wavelengths. Cov qhov zoo nyob rau hauv cov ntawv yog:
● xoom residual birefringence
● Transverse electric teb los ntawm lub teeb propagation
● Nonhygroscopic
● tsawg kawg ib nrab-yoj
Harmonic cim ntxiv mus, tshwj xeeb tshaj yog muaj luv fais fab laser diodes nyob hauv lub µm 1.3 1.55 ntau yam.
Kho qhov muag parametric oscillation.Nrog nws cov nonlinear coefficients siab, lithium niobate yog tus nruab nrab npaum kho qhov muag parametric oscillation.

Phasematching.Meskas tunable wavelengths nyob ib sab wavelength ntau yam, lithium niobate phasematching dab muaj:

● Sab spectral kis xws li 0.4 µm rau 5.0 µm nrog ib OH-haum rau 2.87 µm
● Loj tsis birefringence
● Loj nonlinear coefficients
Qhov txawv zaus nws.Lithium niobate generates tunable infrared wavelengths mus txog ib zaus nws txheej txheem sib txawv. Raug powers 10 nanosecond pulses thiab beams 5-hli yog:

● 30 mJ/mem tes ntawm 0.640 µm rho 40 mJ/mem tes ntawm 1.064 µm los ua 2.5 mJ/mem tes ntawm 1.54 µm
● 32 mJ/mem tes ntawm 0.532 µm rho 32 mJ/mem tes ntawm 0.640 µm los ua 0.25 mJ/mem tes ntawm 3.42 µm

Magnesium Oxide Doped Lithium muaju Niobate (MgO:LiNbO3)
Piv nrog siv lead ua LiNbO3, siv lead ua MgO:LiNbO3 exhibits, xyov zoo rau NCPM zaus doubling (SHG) Nd:Lasers, nws (SFG) thiab kho qhov muag parametric oscillators (OPOs). Cov SHG tshem
laus dua 65% rau pulsed Nd:YAG lasers thiab 45% rau cw Nd:YAG lasers muaj tau tiav nyob rau MgO:LiNbO3 muaju, feem. MgO:LiNbO3 tseem yog ib tug siv lead ua zoo, kho qhov muag parametric oscillators (OPOs) thiab amplifiers (OPAs), quasi-phase-matched doublers, thiab integrated waveguide.
MgO:LiNbO3 tau zoo sib xws zoo nonlinear coefficients los LiNbO3 ntshiab. Nws cov Sellmeier los yog:
n²o (l) = 4.8762+0.11554/ (l² - 0.04674) - x 0.033119 l² (l hauv um)
n²o (l) = 4.5469+0.094779/ (l² - 0.04439) - x 0.026721 l²

Metalaser muaj zoo MgO:LiNbO3 muaju ntau nonlinear optics (NLO) thiab cov kev siv E-O. Cov raug me me ntawm MgO:LiNbO3 muaju yog x (3-10) (3-10) HM (10-30) mm3 OPOs thiab OPAs thiab zaus doubling & nws, thiab 20 x 20 x 1 mm3 rau waveguide substrates. Lwm specs. thiab yog koj thov AR-coatings txog MgO:LiNbO3.
