Non-linear Optical (NLO) crystals supply an enormously adaptable Option for making new wavelengths from present, off-the-shelf laser sources. The optical wavelength spectrum is used by a significant and continuously growing number of applications, from production of clinical lasers, quantum networking & computing by way of to environmental sensing in addition to a lot of Other people.
The choice from the most suitable crystal materials for a supplied application is frequently significantly from trivial; it should really require the thing to consider of many aspects. One example is, a higher nonlinearity for frequency conversion of ultrashort pulses doesn't aid In the event the interaction size is strongly restricted by a large group velocity mismatch along with the very low destruction threshold restrictions the applicable optical intensities.
The hurt Assessment is going to be carried out on an analogous optic (consumer's optic will not be damaged). Tests could cause supplemental charges or guide situations. Speak to Tech Support To learn more.
As a way to use the required CW harm threshold of the optic, it is necessary to grasp the following:
Generally, the crystal materials ought to have a higher optical transparency for all wavelengths included �?one example is, for pump, sign and idler in an optical parametric amplifier.
EKSMA Optics works by using cookies to supply you with the greatest buying knowledge. In the event you keep on to work with our solutions, we will suppose that you choose to conform to the usage of these cookies.
Nonetheless, it’s crucial to Be aware that although BBO crystals can cope with high electricity, they ought to nonetheless be used within their specified energy array to forestall likely problems and guarantee optimal general performance.
the chemical durability; e.g., some crystal resources are hygroscopic, Some others go through chemical modifications when heated inside of a vacuum chamber for software of a dielectric coating
It’s crucial that you stay clear of using abrasive supplies or potent solvents, as these can scratch or or else damage the crystal’s surface. Common cleaning may help retain the crystal’s optical overall performance and prolong its lifespan.
In lieu of decompose the SHG polarization into parts Ex and Ez, The sunshine is usually more info called a rare wave (E'e) using a refractive index, n'e. From the diagram on the best, n'e, which will depend on θ, is indicated via the intersection from the conic area illustrated with the purple ellipse Using the XZ plane.
These crystals are distinctive due to their power to alter the frequency of light passing by means of them, a house that is very desired in numerous fields like laser technologies and quantum physics. The versatility of BBO crystals helps make them a vital ingredient in many Innovative optical devices.
Pulsed lasers with significant pulse repetition frequencies (PRF) might behave equally to CW beams. Sad to say, this is extremely dependent on aspects for example absorption and thermal diffusivity, so there is not any trusted process for deciding any time a high PRF laser will destruction an optic resulting from thermal outcomes.
The 266nm generation refers back to the creation of ultraviolet gentle with a wavelength of 266 nanometers.
The 266nm wavelength features precise interactions that other wavelengths can’t, rendering it indispensable for detecting and studying certain compounds.
