However, in many circumstances, the primary difference in the fundamental and next harmonic pulse velocities can result in just one pulse to considerably lag one other.
Howdy, thanks for calling Thorlabs. The wavelength ranges in the antireflective coatings on these β-BBO crystals align While using the respective wavelength bands that these crystals are optimized for. Requests for customizations might be created by achieving out to us at [email protected]
A: Certainly, BBO crystals show spectacular thermal security, producing them suitable for applications with various temperatures.
The section-matching capabilities of BBO crystals are entitled to Distinctive point out. During the intricate dance of photons, where conversion from a person wavelength to another is usually sought after, the period-matching provided by BBO ensures that Power losses are minimal.
Thorlabs expresses LIDT for CW lasers as being a linear energy density measured in W/cm. On this routine, the LIDT specified to be a linear electric power density could be applied to any beam diameter; one does not should compute an adjusted LIDT to adjust for changes in location dimensions, as demonstrated by the graph to the appropriate. Common linear power density might be calculated using the equation below.
Their high destruction threshold and great thermal balance make them ideal for use in large-energy laser get more info systems, when their broad transparency array lets them to work with a wide selection of laser wavelengths.
The Actual physical, chemical, optical, and thermal properties in the α -BBO are much like People with the BBO crystals, but the α -BBO doesn't exhibit the nonlinear optical Homes due to central symmetry of its crystal composition.
Since the refractive index would not range linearly with frequency in dispersive crystals like β-BBO, it truly is not possible to optimally period match every single frequency during the enter pulse's spectral selection Together with the corresponding second harmonic frequency in the generated pulse.
Frequent cleansing and good storage may also help increase the lifespan of BBO crystals, guaranteeing their ongoing contribution to the sector of optics and photonics.
This calculation assumes a uniform beam intensity profile. You will need to now adjust this energy density to account for hotspots or other nonuniform depth profiles and about work out a most energy density. For reference a Gaussian beam commonly provides a utmost Electricity density that's 2 times that of the one/e2 beam.
This attribute interprets to diminished have to have for intensive thermal management systems, again accentuating Price savings and process simplicity.
Thermal fluctuations are a concern in several experimental and industrial setups. Nevertheless, BBO crystals�?intrinsic thermal steadiness ensures that they don’t just endure but thrive in this sort of ailments.
This is especially critical in Organic and health care investigation in which distinct compounds or cells are tagged with fluorescent markers. The 266nm mild can excite these markers, creating them jump out Obviously against a history, therefore facilitating comprehensive Assessment.
