Optical parametric chirped-pulse amplification (OPCPA): We use OPCPA to determine our objects�?nonlinear conversion performance as well as section-matching angle for your supplied enter wavelength and signal/idler wavelengths.
The temporal stroll-off with the slower pulse with regard to your a lot quicker might be a considerable fraction of the heart beat duration. This can be illustrated in Figure 22.
The SHG light-weight is polarized in the XZ airplane and is orthogonal to both the Eo and the k-vector. Rather then decompose the polarization from the SHG mild into Ex and Ez elements, the electrical area is typically called an extraordinary wave (E'e). The refractive index for this incredible wave, n'e, improvements like a operate of θ. n'e(θ) is usually calculated utilizing the equation in Figure thirteen. The ellipse defining the remarkable index of refraction for a purpose of θ is usually a conic part from the index ellipsoid.
The angular information in the resultant SHG pulse, or beam, within the dimension from the angular filter is lessened from a really perfect case. Within the perpendicular dimension, the SHG beam preserves the angular written content on the enter beam, considering that there’s no angular filter in that dimension. A diverging beam with asymmetric NA’s, i.e. within the horizontal and vertical Proportions, causes an elliptical beam.
The calculation higher than assumes a uniform beam depth profile. You must now think about hotspots inside the beam or other non-uniform intensity profiles and roughly compute a website maximum electric power density.
Filters below or the shape at The underside may be used to aid products research or make more inquiries.
In addition to their use in laser frequency conversion, BBO crystals have discovered apps in electro-optic modulation and quantum optics experiments.
Bodily, when the fundamental spectrum is nicely throughout the reference pulse spectrum, the SHG pulse intensity profile would be the square of the fundamental depth profile, successfully truncating the duration. This case is illustrated in Figure 20.
GWU-Lasertechnik offers all standard nonlinear crystals like LBO, BBO and KTP with a wide number of technical specs. Beside the nicely-established products, progressive crystals like CLBO or BiBO with superb Attributes for e. g. deep-UV era or high-electricity ultrashort pulse lasers are available. Irrespective of if unique pieces for R & D needs are expected or Expense-economical numbers in modest, medium or significant batches with in-time supply for your generation line are essential: GWU’s dedicated support helps you to locate the most effective core elements in your software.
The raw products, commonly a mix of barium carbonate and boric acid, are put inside of a platinum crucible and heated right until they melt. The temperature is then step by step lessened, making it possible for the BBO crystal to type about a number of months. The crystal is then extracted, cut into the specified form, and polished to attain a higher-high-quality optical surface area.
They also have a high destruction threshold, making it possible for them to deal with high-ability laser beams without degradation. These one of a kind Houses make BBO crystals a versatile Software in a variety of optical applications.
GWU-Lasertechnik has more than thirty several years of expertise in distributing laser crystals. Select GWU to reap the benefits of our broad knowledge As well as in-field experience!
Last but not least, the Lower crystals are polished to a clean complete. This polishing course of action not merely improves the aesthetic appearance on the crystals but will also increases their optical Homes by decreasing surface imperfections.
