What would make LBO Exclusive is its mixture of a large transparency vary, extending through the ultraviolet to the far infrared, and an extremely significant harm threshold.
Although the crystal material or coating will not be delicate to drinking water, tiny water droplets could focus laser radiation extra tightly than underneath usual Procedure, and therefore damage the crystal substance.
But LBO has superior transparency, a lot less flaws, and doesn't experience gray monitoring. The result is higher energy and life span capacity. It is usually inexpensive than hydrothermal KTP, so it's begun to interchange KTP in the more demanding purposes.
Possessing the crystal Slice for NCPM and maintaining the crystal at certain temperature, the walkoff angle is nearly zero, consequently it lets to possess a very long crystal and realize fantastic conversion performance. The LBO crystal is usually used to produce next and 3rd harmonics of neudymium centered lasers like Nd:YAG, Nd:YVO4. A further critical application on the LBO crystal is frequency conversion in optical parametric oscillators (OPO).
In terms of the optical Houses of LBO Crystals, they certainly existing an impressive portfolio. The vast transparency array, stretching within the deep ultraviolet to significantly infrared spectrum, permits LBO Crystals to connect with an unlimited variety of laser gentle sources, amplifying their versatility in numerous programs.
The choice from the most fitted crystal product for a offered application is frequently much from trivial; it ought to contain the thing to consider of many facets. As an example, a higher nonlinearity for frequency conversion of ultrashort pulses would not assistance In the event the interaction duration is strongly constrained by a large team velocity mismatch and the small injury threshold restrictions the applicable optical intensities.
SHG and THG for Center and significant electrical power Nd: lasers at 1064 nm for health care, industrial and navy apps
They help these substantial electrical power systems to accomplish their peak functionality while making certain longevity, thanks to their substantial damage threshold.
In the situation of ultrashort pulses the significant group velocity mismatch enforces the use of a shorter crystal, which demands high optical intensities for a given conversion performance.
Overall, the characterization solutions reviewed In this particular chapter give worthwhile insights in to the methods employed for the characterization of LBO nonlinear crystals.
SHG measurement can be utilized to determine the nonlinear optical coefficients of LBO nonlinear crystals, which is important for optimizing their general performance in many apps.
From the context of force, LBO Crystals are usually applied underneath ambient strain problems in most optical purposes. They keep their structural integrity and optical Attributes underneath these ailments, guaranteeing reputable effectiveness.
For client benefit and defense of crystals, common 1" anodized aluminum (Al) mounts is often supplied on request. The mounted crystals is usually even further mounted in a conventional one" mirror mount to be angle tuned for period matching (
Crystals that happen to be non-critically phase-matched inside a crystal oven may perhaps show complications in the event the crystal temperature is improved much too promptly or far too typically. Specifically, anti-reflection coatings here can be destroyed because of unique thermal growth coefficients from the associated resources.
