The TSSG system is a relatively new procedure which has attained reputation for its capacity to deliver higher-good quality crystals with small defect density.
Regardless of whether the crystal substance or coating is just not sensitive to water, small h2o droplets may well concentration laser radiation far more tightly than beneath standard operation, and thus problems the crystal substance.
Lithium triborate (LBO) nonlinear crystal is The most utilised crystal for harmonics technology for short and extended pulse apps. As a consequence of it’s rather tiny walkoff angle extensive crystals might be employed what permits to attain large conversion efficiency. A Unique circumstance of LBO crystal application is often a non-essential period matching (NCPM) for harmonics era.
Medical lasers utilize those Attributes to enable particular methods, or boost upon existing results. An example is working with inexperienced output lasers for BHP operation.
When it comes to the optical Homes of LBO Crystals, they indeed present a powerful portfolio. The wide transparency array, stretching within the deep ultraviolet to significantly infrared spectrum, allows LBO Crystals to communicate with a vast assortment of laser light-weight sources, amplifying their versatility in different programs.
The selection with the most suitable crystal product for the offered software is usually significantly from trivial; it should require the consideration of numerous aspects. One example is, a superior nonlinearity for frequency conversion of ultrashort pulses will not assistance In the event the conversation duration is strongly constrained by a significant group velocity mismatch along with the very low damage threshold limits the applicable optical intensities.
It consists of employing a seed crystal to initiate crystal development from the supersaturated Alternative. The TSSG method can generate crystals with managed defect density and orientation, which happens to be essential for attaining ideal period-matching situations.
Irrespective of whether it’s a lower-temperature scientific experiment or even a superior-temperature industrial method, you are able check here to depend on LBO Crystals to deliver dependable functionality. Their capability to take care of their nonlinear optical Qualities throughout a broad temperature selection additional augments their flexibility.
Variety II NCPM OPO pumped by a XeCl excimer laser at 308nm has reached 16.five% conversion effectiveness, and moderate tunable wavelength ranges is usually received with distinct pumping sources and temperature tuning.
Shorter wavelength gentle with better Electrical power pulses provides improved precision and smaller sized place dimensions than industrial toughness neodymium or CO2 lasers, So reaching finer resolution and accuracy.
Inspect the crystal floor for dust and stains by Keeping it close to a vivid seen-light source. Viewing at distinct angles may help see scattering from dust and stains. The crystal area has to be cleaned as described under if dust and stains are found.
The magnitude on the efficient nonlinear coefficient relies on the nonlinear tensor elements and over the utilized section-matching configuration. A higher nonlinearity is crucial specifically if the achievable optical intensities are minimal.
SHG measurement can also be applied to determine the crystal high-quality and defects, for example domain framework and non-uniformity.
They are able to endure sizeable heat with none considerable performance reduction, ensuring that your optical system stays reliable and successful even in demanding scenarios.
