A Simple Key For LBO Crystal Unveiled
Blog Article
LBO is a wonderful NLO crystal for OPOs and OPAs with a greatly tunable wavelength variety and large powers. The special Qualities of type I and kind II period matching in addition to the NCPM go away a big room from the exploration and programs of LBO's OPO and OPA.
LBO has this sort of terrific transmittance that it can even be utilized to deliver 266 nanometer light, although the absorption under 300nm is normally far too substantial with the conversion being valuable. In addition it shows Excellent effectiveness for frequency conversion usually.
These characteristics decrease the alignment sensitivity on the optical system and make certain far better beam propagation. The a lot less stringent alignment prerequisites and better beam high quality conferred by these attributes usually tip the scale in favor of LBO Crystals over other nonlinear optical crystals.
Ordinarily, the crystal product should have a high optical transparency for all wavelengths concerned �?by way of example, for pump, signal and idler in an optical parametric amplifier.
Just about the most crucial Houses of LBO nonlinear crystals is their capacity to attain period-matching for economical frequency conversion. Period-matching will be the situation the place the wave vectors of the elemental and harmonic waves match, enabling the conversion of the fundamental frequency to the harmonic frequency.
Optical parametric oscillation (OPO) is a nonlinear approach that consists of the conversion of the higher-Strength photon into two decrease-Vitality photons inside a resonant cavity. LBO nonlinear crystals Possess a higher nonlinear click here coefficient, which makes them ideal for successful OPO.
SHG and THG for middle and superior power Nd: lasers at 1064 nm for medical, industrial and navy programs
No matter whether it’s a very low-temperature scientific experiment or a substantial-temperature industrial system, you'll be able to rely on LBO Crystals to deliver steady effectiveness. Their potential to keep up their nonlinear optical Homes throughout a large temperature assortment more augments their versatility.
Working with our advertising and marketing package deal, you may display your emblem, further more below your product or service description, and these will been witnessed by many photonics specialists.
Nonlinear Crystals of either β-barium borate (BBO) or lithium triborate (LBO) are employed for frequency conversion of laser sources. BBO crystals element thicknesses from 0.2mm to 0.5mm to minimize team velocity mismatch and are perfect for frequency doubling or tripling of Ti:Sapphire and Yb:doped laser pulses. The vital and noncritical section matching LBO crystals are ideal for next or 3rd harmonic generation of Nd:YAG and Yb:doped lasers.
Along with that, the high problems threshold �?the flexibility of LBO Crystals to face up to significant-intensity laser beams devoid of compromising their structure or general performance �?can be a much-appreciated high quality, particularly in significant-electric power laser applications.
Just about the most common programs is frequency doubling, exactly where LBO Crystals competently convert the frequency of a high electrical power laser, correctly halving the wavelength and opening up a spectrum of prospects for laser apps.
PL spectroscopy may be used to determine impurities and defects in LBO nonlinear crystals which can have an effect on their effectiveness in different apps. PL spectroscopy can even be applied to ascertain the crystal high-quality and homogeneity.
Crystal development is a crucial step while in the production of large-high-quality LBO nonlinear crystals. The selection of crystal progress system can considerably effect the crystal excellent, defect density, and optical Attributes of your ensuing crystal.
