SHG measurement is really a commonly applied technique for characterizing the nonlinear optical Attributes of LBO nonlinear crystals. SHG measurement requires shining a laser beam of a certain wavelength on to the crystal and measuring the depth of the next-harmonic wave produced by the crystal.
You must think about the wavelength and energy of your respective laser resource and go with a crystal that is definitely transparent with the given wavelength and can face up to the laser electricity. And lastly, other factors such as the thermal security, optical homogeneity, and nonlinear optical coefficient in the crystal also need to be considered.
Lithium triborate (LBO) nonlinear crystal is Among the most made use of crystal for harmonics generation for brief and extended pulse applications. Because of it’s relatively modest walkoff angle very long crystals could be employed what allows to accomplish significant conversion performance. A special situation of LBO crystal application is actually a non-crucial stage matching (NCPM) for harmonics technology.
Raman spectroscopy can be employed to detect impurities and defects in LBO nonlinear crystals that can impact their overall performance in various applications. Raman spectroscopy may also be applied to determine the crystal top quality and phase purity.
The flux system is yet another common procedure that entails dissolving the starting elements in the flux and gradually cooling the answer to kind crystals.
Be sure to find your shipping state to view by far the most exact inventory facts, and to ascertain the proper Edmund Optics gross sales Business office for your personal buy.
EKSMA Optics takes advantage of cookies to provde the greatest buying working experience. In the event you carry on to work with our expert services, we website will suppose that you just comply with the use of this sort of cookies.
These conditions, nonetheless, aren’t set in stone and mostly depend on the supposed software of the crystal as well as intricacies in the laser program style and design. Usually, regarding temperature,
Variety II NCPM OPO pumped by a XeCl excimer laser at 308nm has realized 16.5% conversion effectiveness, and average tunable wavelength ranges is often received with unique pumping sources and temperature tuning.
Non-linear Optical (NLO) crystals offer an enormously adaptable Alternative for generating new wavelengths from current, off-the-shelf laser resources. The optical wavelength spectrum is used by a large and regularly increasing number of apps, from production of healthcare lasers, quantum networking & computing as a result of to environmental sensing as well as many others.
Along with that, the substantial damage threshold �?the power of LBO Crystals to resist significant-intensity laser beams without having compromising their composition or efficiency �?is actually a Significantly-appreciated quality, particularly in higher-ability laser purposes.
In the longer wavelength location on the spectrum, LBO is employed for tunable OPO’s to yield close to-infrared radiation.
The most typical method for obtaining section-matching in LBO nonlinear crystals is angle tuning, the place the crystal is rotated to locate the optimal angle that satisfies the period-matching condition.
The comprehension of these procedures is essential for the look and optimization of crystal expansion procedures as well as the manufacture of superior-good quality LBO nonlinear crystals for several apps in optics and photonics.
