This information dives deep into the benefits and exclusive Houses of BBO crystal and its paramount importance in effective frequency doubling and harmonics generation at 266nm.
The selection with the most fitted crystal materials for the given software is usually far from trivial; it need to entail the thought of many elements. As an example, a significant nonlinearity for frequency conversion of ultrashort pulses isn't going to enable if the conversation length is strongly limited by a considerable group velocity mismatch plus the minimal injury threshold limitations the relevant optical intensities.
Thorlabs provides a wide variety of optics optimized for use with femtosecond and picosecond laser pulses. Remember to see underneath To find out more.
One of many defining attributes of BBO crystals is their superior problems threshold. This means that they can endure high levels of laser ability without the need of going through degradation or damage.
Superior-quality crystals may have much less defects and supply superior functionality, although a reliable supplier will stand at the rear of their goods and give support when essential. Very good customer service could also make the paying for approach smoother and much more enjoyable.
These resilience makes sure that its nonlinear Qualities aren't simply compromised, rendering it a favorite in environments exactly where consistency and dependability are paramount.
Most of the standard nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the elemental laser radiation can be found from inventory. Client-certain Proportions and AR coatings also are supplied at competitive rates.
Along with their use in laser frequency conversion, BBO crystals have found applications in electro-optic modulation and quantum optics experiments.
Just about every aspect of BBO, from its atomic structure to its wide software spectrum, underscores its pivotal job in modern science and technology.
The next is often a standard overview of how laser induced damage thresholds are measured read more and how the values could be utilized in determining the appropriateness of an optic to get a specified software. When picking optics, it is vital to comprehend the Laser Induced Problems Threshold (LIDT) with the optics being used. The LIDT for an optic enormously depends on the kind of laser you happen to be working with. Steady wave (CW) lasers normally trigger problems from thermal results (absorption either inside the coating or within the substrate).
When comparing an LIDT specified for the pulsed laser for your laser, it is important to understand the subsequent:
Having said that, in lots of circumstances, the main difference in the basic and second harmonic pulse velocities may cause just one pulse to drastically lag another.
When an input pulse's spectral array is equal to or narrower as opposed to reference pulse, the produced next harmonic pulse features a period that may be shorter by a factor of 1/√2 as well as a spectral width that is definitely broader by an element of √two.
Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are elements with a relatively sturdy nonlinearity. They are sometimes useful for nonlinear frequency conversion in addition to for electro-optic modulators. Equally elements can be found in congruent As well as in stoichiometric form, with essential differences concerning periodic poling and photorefractive results (see underneath). Lithium niobate and tantalate will be the most often utilised materials in the context of periodic poling; the ensuing elements are identified as PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT for your stoichiometric versions.
