LilO3 Crystal - An Overview
Blog Article
ed �?Coating possibilities: AR, BBAR or P-coating Lithium Iodate (LilO3) Crystal is often a uniaxial nonlinear crystal with superior nonlinear coefficients and a broad optical clear range of 0.5μm to 5.0μm. It's extensively applied for the SHG from the minimal and medium electricity Ti:Sapphire, Alexandrite, Cr:LiSrAlF6 and Cr:LiCaAlF6 lasers. It is additionally preferable for that SHG and THG of Nd:YAG lasers and car-correlators for measuring extremely-limited pulse width. In some cases, it is operated for optical parametric oscillation to obtain continuously tunable lasers within the wavelength range between 0.
alpha -LiIO3 crystal is developed with the consistent temperature evaporation approach. Brillouin scattering experiment is carried out to study the elastic Attributes of your crystal alpha -LiIO3. We get hold of all of 6 elastic constants in the crystal alpha -LiIO3 by using two cubic samples.

The nonlinear coefficients of lithium iodate are already calculated, relative to quartz, because of the Maker fringe procedure.for the elemental wavelength 1.064μ. It has also been determined that d31 and d33 hold the similar indication.

Significant interest has just lately been drawn towards the iodates owing to the massive nonlinear optical interactions (next harmonic and photoelastic) documented in α�?HIO three . Inside the existing function, lots of the photoelastic and piezoelectric constants and associated Houses of one‐crystal lithium iodate LiIO 3 are determined. The acousto‐optic figure of benefit for LiIO three continues to be observed to be only about 15% of that for α�?HIO three , earning the material unattractive as an acousto‐optic medium.

According to the linear piezoelectric coupling equation, the relations concerning the ultrasonic velocities and elastic moduli are acquired. The velocities of longitudinal and shear waves which propagate together distinct symmetry Instructions of α-LiIO3 crystal are determined by the heartbeat here echo overlap method. The elastic moduli CijE and CijD are then deduced, the values of which （×10-10N/m2�?are
We obtain all of five elastic constants with the crystal α-LilO3. by using two cubic samples. As a result the obtained elastic constants are just like the Other people' success. Through the attained elastic constants it is feasible to build the slowness curves.
Its hexagonal structure and exceptional optical homogeneity help it become perfect for significant laser components. Nevertheless, LiIO3 is highly hygroscopic and calls for dry storage and sealed housing for prolonged toughness. Photonics On Crystals (POC) makes certain significant-high-quality fabrication to fulfill industry requirements for precision optics.
Using a issue-cost and dipole design, the spontaneous polarization Ps of α-LiIO3 is calculated to become parallel to the way where the apices of IO-3 pyramids are pointed.

LiIO3 is usually used in OPO techniques as a result of its extensive transparency array and outstanding stage-matching Attributes.
Photoinduced polarization is obtained in a very lithium iodate single crystal via the simultaneous software of the dc discipline and illumination from the uv source. The darkish depolarization and photodepolarization present-day decay qualities with the polarized samples have already been analyzed intimately in this paper.
LiIO3 crystals are thoroughly Employed in frequency-doubling and tripling processes for lasers running during the UV and visual ranges. This functionality is particularly useful in laser spectroscopy and bioimaging applications.
