LBO is a wonderful NLO crystal for OPOs and OPAs that has a commonly tunable wavelength array and higher powers. The special properties of type I and sort II period matching together with the NCPM depart an enormous space during the investigation and programs of LBO's OPO and OPA.
You'll want to take into account the wavelength and electricity of the laser source and pick a crystal which is clear for the provided wavelength and may withstand the laser ability. And finally, other components like the thermal security, optical homogeneity, and nonlinear optical coefficient from the crystal also must be considered.
We offer precision oven and temperature controller to keep up LBO crystals in a preset temperature for noncritical phasematching (NCPM) for SHG and OPO/OPA. Crystals may very well be pre-installed in to the oven gratis inside our manufacturing unit for your personal convenience.
Notice that whether or not the nominal intensity is beneath the nominal injury threshold, there may be problems because of fluctuations within the beam power or local intensity (e.g., if a beam profile has “sizzling places�?, or as a result of isolated defects within a crystal, that happen to be a lot more delicate as opposed to normal crystal substance.
The excellent optical homogeneity and lack of inclusions in GAMDAN content suggest good undistorted wavefront output from a gadget. LBO has an exceptionally high internal damage threshold as a result of its very low absorption. That assets also avoids beam distortion from thermal expansion.
The strategy is likewise comparatively rapidly and can develop crystals with large growth costs. On the other hand, the TSSG method necessitates careful control of the cooling rate, seed crystal dimensions, and focus of the starting off elements to take care of uniform crystal advancement.
LBO crystal (Lithium triborate) is often a non-linear optical product of option for frequency changing superior electrical power lasers with its adhering to major characteristics:
UV lasers excel at marking. Resources which have been if not clear, including prevalent glass, lenses, and prisms, various forms of plastics and organic and inorganic supplies may be exactly marked with frequency tripled gentle.
The idea of these properties is vital for designing and increasing high-high quality LBO nonlinear crystals for various applications
Nonlinear Crystals of possibly β-barium borate (BBO) or lithium triborate (LBO) are used for frequency conversion of laser sources. BBO crystals element thicknesses from 0.2mm to 0.5mm to minimize group velocity mismatch and are ideal for frequency doubling or tripling of Ti:Sapphire and Yb:doped laser pulses. The essential and noncritical phase matching LBO crystals are ideal for 2nd or third harmonic technology of Nd:YAG and Yb:doped lasers.
In spectroscopy, OPA is utilized to crank out tunable gentle sources for numerous apps, like chemical Examination and materials characterization. In telecommunications, OPA is used to amplify and transform indicators in optical interaction methods.
g. 20 μm. The group velocity mismatch from the thicker substrate materials may well not matter, as the nonlinear interaction usually takes spot only in The skinny crystal. The substrate only serves to mechanically stabilize The skinny nonlinear crystal.
In addition, LBO Crystals have built sizeable contributions to the realm of optical parametric oscillation, a procedure essential for producing tunable light-weight resources. Below, they function a System to the incident mild to create two check here new light beams, each carrying different frequencies.
The TSSG strategy allows for the manufacture of large-high-quality LBO crystals with minimal defect density and exceptional optical Qualities. Using a seed crystal helps to regulate the crystal orientation and defect density, bringing about enhanced crystal high-quality.
