5 Simple Statements About LBO Crystal Explained
Blog Article
The optimum angle depends upon the type of nonlinear method, the wavelength, along with the crystal thickness. Other techniques for achieving period-matching in LBO nonlinear crystals contain temperature tuning and quasi-stage matching.
You'll want to consider the wavelength and energy of one's laser source and opt for a crystal that may be clear with the presented wavelength and can face up to the laser electricity. And lastly, other elements such as the thermal steadiness, optical homogeneity, and nonlinear optical coefficient with the crystal also should be thought of.
the chemical toughness; e.g., some crystal components are hygroscopic, Many others bear chemical improvements when heated in a vacuum chamber for application of the dielectric coating
retains a big stock of LBO crystals which can be delivered within 1 week upon receipt of the purchase get. (
It's value noting that the characterization solutions reviewed On this chapter are not restricted to LBO nonlinear crystals and may be applied to other nonlinear crystals in addition.
In essence, the thermal security of LBO Crystals can be a testomony to their resilience and trustworthiness, building them a favourite amongst experts and engineers within the world.
Crystals for NCPM at an elavated temperature is often premounted within an oven with precision controller. Crystals applied at ~ 20 - 50 oC can also be premounted in a very suitable water-cooled or TEC (ThermoElectric Cooler) cooled mount on ask for.
Too much optical intensities all through Procedure might instantly destruction a crystal. Sad to say, nonlinear crystals generally need to be operated not considerably from their optical injury threshold to obtain a adequately large conversion effectiveness. This implies a trade-off involving conversion efficiency and crystal life span.
Additionally, LBO Crystals boast a significant nonlinear coefficient. This trait is significant in nonlinear optical processes for instance frequency doubling, wherever it facilitates successful conversion from the incident light to a unique frequency.
Nonlinear Crystals of both β-barium borate (BBO) or lithium triborate (LBO) are useful for frequency conversion of laser resources. BBO crystals aspect thicknesses from 0.2mm to 0.5mm to attenuate team velocity mismatch and are perfect for frequency doubling or tripling of Ti:Sapphire and Yb:doped laser pulses. The significant and noncritical phase matching LBO crystals are read more ideal for second or third harmonic generation of Nd:YAG and Yb:doped lasers.
However, if the applying requires, these crystals may endure sure elevated force ailments. It is usually advisable to refer to having a crystal professional or make reference to specific company tips to determine the optimal disorders in your distinct LBO Crystal and application.
Numerous Attributes of the nonlinear crystal is often critical for an software e.g. in nonlinear frequency conversion:
SHG measurement may also be utilised to find out the crystal good quality and defects, for example area framework and non-uniformity.
Inside of a nutshell, LBO is a sport-modifying nonlinear optical crystal that is definitely indispensable in right now’s optical landscape.
