Crylink is undoubtedly an open up System, equally as our mission is to attach value, Crylink believes that every human being and each company has unique worth, and we hope to attach with beneficial you to provide price and mirror value jointly.
Having said that, it’s important to Observe that though BBO crystals can transmit UV gentle, they ought to be taken care of with care when Utilized in UV applications to forestall prospective damage to the crystal and ensure basic safety.
Sad to say, it might be very hard to compare the LIDT specification of the optic to your laser. There are actually numerous regimes by which a pulsed laser can damage an optic which is based over the laser's pulse size. The highlighted columns within the desk under outline the relevant pulse lengths for our specified LIDT values.
) is The true secret for BBO to get substantial conversion performance. Restricted concentration of laser beam just isn't suggested.
BBO crystals may be cleaned employing a delicate fabric or air blower. For stubborn stains, a delicate detergent or isopropyl alcohol can be used. It’s important to stay away from working with abrasive components that would scratch the crystal’s surface. When cleaning BBO crystals, it’s important to use a gentle, circular motion to stay away from scratching the surface area.
Superior destruction threshold: BBO crystals have superior problems limitations that will arise for their high major and common electrical power with out degradation or injury.
Filters underneath or the form at the bottom may be used to assist item search or make further inquiries.
Cleansing BBO crystals is a fragile approach that needs treatment to prevent detrimental the crystal’s surface. A delicate cloth or lens tissue moistened which has a mild solvent, such as isopropyl Liquor, can be used to gently wipe the surface area from the crystal.
A5: Certainly, BBO crystals have superb thermal security and can preserve their Homes at area temperature. Therefore they may be Employed in a variety of environments with out requiring Unique temperature control.
A3: Certainly, BBO crystals have a large transparency range that extends in the ultraviolet spectrum. This tends to make them ideal for apps that need ultraviolet light, which include UV spectroscopy and UV laser programs.
Excessive optical intensities throughout Procedure may well right away destruction a crystal. Regretably, nonlinear crystals generally have to be operated not far from their optical harm threshold to achieve a adequately significant conversion effectiveness. This means a trade-off among conversion efficiency and crystal life span.
The creation of Beta-Barium Borate (BBO) crystals get more info is a fancy and meticulous method that needs a high volume of precision and skills. This method, generally known as the flux technique, commences Using the planning of a mix of barium borate and barium fluoride.
For that reason, the second harmonic pulse spectrum, demonstrated on the proper, contains a spectral width around similar to The perfect scenario. Preferably, every frequency in the basic pulse spectrum will be simultaneously section matched.
flux-grown KTP and RTP with its significant nonlinearity, also in variants with large grey tracking resistance
