Electrooptic PLZT ceramics in infrared: Properties and applications

2.79 μm erbium laser with lead–lanthanum zirconate titanate ceramics electro-optic Q-switching output coupler

“…11 A laser with an Er:Cr:YSGG single crystal rod with 90 mm in length and 4 mm in diameter was used in the experiments. The laser cavity ͑40 cm in length͒ was formed by a highly reflective dielectric rear mirror (rϭ6 m) and by a PLZT element with a 3 mm thickness and a 6ϫ6 mm 2 optical aperture ͑Fig.…”

Effects of PMN/PT ratio on optical and electro-optic properties of PLMNT transparent ceramics

“…Their EO effects are found to be very sensitive to composition variation. The influence of La content near the morphotropic phase boundary (MPB) has been studied comprehensively [6]. However, few works have been carried out to systemically investigate the influence of PMN/PT ratio on their performance of PLMNT transparent ceramics.…”

“…As one of the most important branches of EO transparent ceramics, La 3 þ doped PbZrTiO 3 (PLZT) ceramics have been systemically investigated for decades [3][4][5][6][7]. Nevertheless, the PLZT transparent ceramics show significant field-induced detention and high polarization-dependent scattering loss.…”

“…Electro-optic (EO) effect, i.e., the birefringence variation caused by an externally applied electric field, has potential applications in optical devices [1][2][3][4][5][6][7][8][9][10][11][12]. As EO benchmark materials, LiNbO 3 single crystals have been widely used in the field of current telecommunication.…”

“…Due to low EO coefficient and high driving voltage, applications in low-voltage-driving optical devices have been dramatically limited. However, the EO transparent ceramics present a promising application in the low-voltage-driving optical system because of their remarkable EO effect with low half-wave voltage and high optical transparency [1][2][3][4][5][6].…”
