The exceptional angle will depend on the sort of nonlinear procedure, the wavelength, as well as the crystal thickness. Other techniques for attaining period-matching in LBO nonlinear crystals incorporate temperature tuning and quasi-section matching.
The understanding of these methods is very important for the design and optimization of LBO nonlinear crystals for many programs in optics and photonics.
Lithium triborate (LBO) nonlinear crystal is The most applied crystal for harmonics generation for short and extended pulse applications. As a consequence of it’s rather smaller walkoff angle very long crystals may be utilized what permits to attain superior conversion performance. A Particular circumstance of LBO crystal software is really a non-vital stage matching (NCPM) for harmonics era.
The level of the solvent could be modified for different crystal sizing And so the lens tissue is retained damp for the entire drag but there's not any seen trace of solvent within the crystal floor following the drag is completed. Inspect the area and repeat if needed, but only use Each individual sheet of lens tissue as soon as.
It is actually really worth noting which the characterization procedures discussed During this chapter usually are not restricted to LBO nonlinear crystals and may be applied to other nonlinear crystals too.
All round, The combination of LBO Crystals into laser technological know-how has pushed the boundaries of what we are able to realize with mild, lights The trail in direction of a brighter, more illuminated future.
Crystals for NCPM at an elavated temperature may be premounted in an oven with website precision controller. Crystals made use of at ~ twenty - 50 oC can also be premounted inside of a compatible water-cooled or TEC (ThermoElectric Cooler) cooled mount upon request.
These circumstances, having said that, aren’t set in stone and largely rely upon the intended application from the crystal as well as the intricacies in the laser program style and design. Normally, concerning temperature,
This confluence of Excellent optical Attributes empowers LBO Crystals to fulfill and exceed the calls for of recent optics, placing the stage for groundbreaking discoveries and innovations within the realm of light.
Past significant power lasers, this thermal security extends LBO Crystals�?applicability to your big selection of environments with different temperature conditions.
LBO is phase matchable to the SHG and THG of Nd:YAG and Nd:YLF lasers, using either variety I or variety II conversation. For the SHG at room temperature, type I phase matching is usually arrived at and it has the maximum effective SHG coefficient in the principal XY and XZ planes in a wide wavelength range from 551 nm to about 3000 nm.
g. twenty μm. The group velocity mismatch while in the thicker substrate product may not subject, as the nonlinear interaction can take place only in the thin crystal. The substrate only serves to mechanically stabilize the thin nonlinear crystal.
On top of that, LBO Crystals have manufactured considerable contributions towards the realm of optical parametric oscillation, a system vital for building tunable gentle resources. Listed here, they function a platform for that incident light-weight to generate two new mild beams, Just about every carrying various frequencies.
They show good homogeneity about large volumes and also have a high damage threshold, but are hygroscopic and also have a lower nonlinearity.
