Higher-precision laser microfabrication is a way exactly where components are processed and modified on the microscopic scale. This process requires a laser source that could create particularly targeted and specific beams of sunshine. The 266nm wavelength is particularly well suited for this on account of its brief wavelength, which makes sure that the laser beam might be centered to an extremely little location size.
A2: Sure, extended publicity to humidity can degrade the optical efficiency of BBO crystals. Humidity can lead to water absorption about the crystal surface, that may affect its optical Attributes.
So as to use the specified CW damage threshold of the optic, it is necessary to grasp the subsequent:
In summary, BBO crystals are a fascinating and functional materials which has significantly advanced the sphere of optics and photonics. By understanding their Attributes and the way to take care of them, we can go on to harness their opportunity and travel additional developments in optical technology.
The 266nm technology makes certain that these interactions are finely tuned, permitting researchers to glean insights with Increased precision. No matter whether it’s in learning intricate molecules, pinpointing the Houses of recent products, or in environmental checking, the BBO crystal’s capacity to produce 266nm light amplifies the depth and precision of spectroscopic studies.
You should Take note that We've got a buffer constructed between the specified hurt thresholds on the internet and the checks which Now we have completed, which accommodates variation amongst batches. On ask for, we can offer personal test info in addition to a testing certificate.
The spatial wander-off angle relies on the dimensions on the beam as well as crystal size. Whilst the angle could be significant, it is normally small, typically about the get of 10 mrad, and can a-BBO Crystal be neglected.
The destruction Examination is going to be carried out on an identical optic (client's optic will not be weakened). Screening may perhaps end in more fees or lead periods. Call Tech Support To learn more.
Since the refractive index isn't going to range linearly with frequency in dispersive crystals like β-BBO, it's impossible to optimally stage match every frequency within the enter pulse's spectral assortment Together with the corresponding 2nd harmonic frequency within the generated pulse.
The temporal stroll-off on the slower pulse with regard to your more rapidly can be a considerable portion of the heart beat period. This can be illustrated in Figure 22.
As will probably be talked over down below, You will find a concentrating numerical aperture (NA) limitation to the SHG phase-matching system specifically analogous for the spectral stage matching limitation mentioned during the previous portion (
This wonderful-tuning capability implies that BBO crystals can cater to both equally generic and highly specialized wants with equivalent finesse.
When laser gentle is targeted to some spot, the diameter of the beam midsection could be the focal place dimension, and the rate at which The sunshine diverges through the beam waist is associated with the Rayleigh range (zR).
This text dives deep into the benefits and special Houses of BBO crystal and its paramount importance in effective frequency doubling and harmonics era at 266nm.
