The TSSG technique is a relatively new system which has gained attractiveness for its capability to make large-excellent crystals with very low defect density.
The acceptance angle on the crystal is yet another crucial determinant. A crystal with a bigger acceptance angle, like LBO, calls for significantly less precise alignment, which makes it simpler to combine into your system. The injury threshold of your crystal is Similarly essential, especially in significant-power laser programs.
Lithium triborate (LBO) nonlinear crystal is One of the more made use of crystal for harmonics technology for brief and extended pulse purposes. As a result of it’s fairly smaller walkoff angle lengthy crystals can be applied what permits to obtain higher conversion effectiveness. A special situation of LBO crystal software is usually a non-crucial stage matching (NCPM) for harmonics era.
Possessing the crystal cut for NCPM and preserving the crystal at certain temperature, the walkoff angle is sort of zero, consequently it will allow to have a really extensive crystal and realize excellent conversion effectiveness. The LBO crystal is generally utilized to make 2nd and third harmonics of neudymium centered lasers like Nd:YAG, Nd:YVO4. An additional vital application in the LBO crystal is frequency conversion in optical parametric oscillators (OPO).
Almost all of the regular nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the fundamental laser radiation can be obtained from inventory. Buyer-specific Proportions and AR coatings will also be available at aggressive prices.
A click here standard strategy for obtaining ultrathin crystals is usually to 1st optically Get hold of a thicker nonlinear crystal with some substrate (e.g. of fused silica) and then to shine the crystal right down to the necessary thickness of e.
LBO can reach both temperature NCPM and spectral NCPM (with a very vast spectral bandwidth) at 1300 nm. That is favorable for that SHG of incredibly broadband or ultrafast pulses at ~ 1300 nm.
You should use "Add to Cart" to put the exciting products in the procuring cart. Look at with on the net payment or check with us for the prices/availability by using the searching cart.
If the crystal surfaces are still “filthy�?after the above mentioned cleaning methods, the surfaces might have been harmed. Be sure to Call us for rework on the crystals.
LBO Crystals have cemented their standing as an integral part of the laser marketplace, contributing drastically to developments in laser technologies. Which has a substantial injury threshold and outstanding optical homogeneity, LBO Crystals can endure the high-intensity outputs that happen to be commonplace in large-electric power laser systems, effectively enabling these techniques to conduct optimally without the need of danger of damage to their elements.
Nonetheless, if the application needs, these crystals may withstand specific elevated force disorders. It is often advised to consult having a crystal skilled or check with specific company guidelines to ascertain the exceptional circumstances for your specific LBO Crystal and software.
The magnitude of the effective nonlinear coefficient depends on the nonlinear tensor parts and over the used phase-matching configuration. A superior nonlinearity is significant specifically if the achievable optical intensities are very low.
The commonest system for accomplishing stage-matching in LBO nonlinear crystals is angle tuning, exactly where the crystal is rotated to locate the ideal angle that satisfies the phase-matching ailment.
The BO3 teams are organized within a triangular configuration, forming a 6-membered ring within the crystal framework. The Li ions occupy the interstitial websites concerning the BO3 groups.
