BBO crystals are grown utilizing the flux system, a procedure that entails melting raw components at superior temperatures. The molten materials is then slowly but surely cooled to form a crystal. This method demands exact Charge of temperature and cooling amount to ensure the crystal’s high quality and integrity.
Thorlabs provides a wide selection of optics optimized to be used with femtosecond and picosecond laser pulses. Make sure you see under For more info.
As the second harmonic light propagates, its energy flows in a distinct direction than that of the elemental mild.
This has don't just expanded the capabilities of existing systems but has also paved how For brand spanking new innovations.
If the crystal surfaces are still “soiled�?just after the above mentioned cleansing procedures, the surfaces might have been broken. Be sure to Get hold of us for rework from the crystals.
The slicing angle relies upon on the popular period-matching difficulty for frequency conversion applications. Stage matching describes matching the period speeds of assorted beams related to nonlinear processes so they Make up constructively in excess of fars away In the crystal.
Given these purposes, it’s obvious why BBO, with its inherent capacity to successfully make the 266nm wavelength, is so highly prized. The crystal’s one of a kind nonlinear optical Houses help the conversion of other wavelengths in to the coveted 266nm mild, making sure that researchers and industries have use of this very important Software.
A5: Of course, BBO crystals have exceptional thermal security and might maintain their Homes at room temperature. Consequently they can be used in an array of environments without having requiring Particular temperature Management.
If click here you don't locate the acceptable products and solutions above, it's possible you'll allow us to know your requirements or programs in the shape under. Our revenue or technical team will get back again for you immediately.
As Beforehand stated, pulsed lasers typically induce a unique type of harm to the optic than CW lasers. Pulsed lasers typically never warmth the optic adequate to wreck it; in its place, pulsed lasers develop powerful electrical fields able to inducing dielectric breakdown in the material.
The position of your inexperienced curve depends upon θ. In this instance, the angle θ has long been tuned to offer a refractive index for 515 nm light that matches the refractive index for 1030 nm light. This tuning angle is as a result optimized for Type-I SHG phase matching along with a elementary-frequency input beam of 1030 nm.
In addition to their significant injury threshold, BBO crystals also show outstanding thermal and chemical steadiness. They are able to face up to a wide range of temperatures and resist degradation from different chemical interactions.
Regardless of whether the crystal substance or coating is not delicate to drinking water, compact water droplets might emphasis laser radiation much more tightly than below ordinary Procedure, and therefore problems the crystal substance.
