Crystal life time can even be strongly dependent on the fabric high quality, although selected degradation phenomena appear to be intrinsic constraints of the material.
The acceptance angle from the crystal is yet another important determinant. A crystal with a larger acceptance angle, like LBO, needs less specific alignment, which makes it easier to combine into your system. The damage threshold on the crystal is equally vital, significantly in higher-electric power laser devices.
Also, it may be hugely appealing to utilize a crystal substance that may be critically stage-matched at home temperature due to the fact noncritical phase matching often will involve the Procedure of your crystal inside of a temperature-stabilized crystal oven. Even so, the feasibility of important period matching may very well be provided only for adequately superior peak powers.
Previous although not the very least, superior optical homogeneity makes sure uniform light-weight propagation with the crystal, leading to better beam excellent and much less distortions.
Most of the standard nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the basic laser radiation are offered from inventory. Consumer-distinct dimensions and AR coatings will also be presented at aggressive costs.
A typical technique for obtaining ultrathin crystals is to very first optically Make contact with a thicker nonlinear crystal with some substrate (e.g. of fused silica) after which you can to shine the crystal down to the expected thickness of e.
EKSMA Optics uses cookies to give you the most effective browsing practical experience. Should you continue on to employ our solutions, We'll believe which you conform to the usage of this kind of cookies.
Whether it’s a lower-temperature scientific experiment or possibly a large-temperature industrial system, you'll be able to rely on LBO Crystals to deliver regular effectiveness. Their capability to maintain their nonlinear optical Homes across a broad temperature vary even further augments their versatility.
L-B-O, what exactly is it good for? Unquestionably the ideal frequency doubling and tripling crystal if you are searhing for quite possibly the most sturdy and destruction resistant content.
Nonlinear Crystals of either β-barium borate website (BBO) or lithium triborate (LBO) are employed for frequency conversion of laser resources. BBO crystals attribute 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 crucial and noncritical phase matching LBO crystals are ideal for 2nd or 3rd harmonic technology of Nd:YAG and Yb:doped lasers.
Lithium Triborate LiB305or LBO is a recently made nonlinear optical crystal.It is unique in several elements,In particular its broad transprency selection,reasonably high nonlinear coupling,large damage threshold and very good chemical and mechanical Attributes.
For the lengthier wavelength region of the spectrum, LBO is useful for tunable OPO’s to generate in the vicinity of-infrared radiation.
SHG measurement will also be applied to determine the crystal top quality and defects, for example domain construction and non-uniformity.
Crystals which are non-critically phase-matched inside a crystal oven could exhibit issues if the crystal temperature is transformed way too promptly or far too generally. Specifically, anti-reflection coatings can be destroyed on account of distinct thermal expansion coefficients with the included components.
