The amount of the solvent may be modified for numerous crystal dimension so the lens tissue is held moist for the entire drag but there's not any seen trace of solvent on the crystal surface after the drag is concluded. Inspect the surface area and repeat if necessary, but only use Each and every sheet of lens tissue the moment.
BBO crystals are developed using the flux method, a process that entails melting raw materials at substantial temperatures. The molten substance is then slowly but surely cooled to type a crystal. This method involves specific Charge of temperature and cooling amount to ensure the crystal’s top quality and integrity.
5 mm to minimize team velocity mismatch and are ideal for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The essential and noncritical section matching LBO crystals are ideal for next or third harmonic era of Nd:YAG and Yb:doped lasers.
) is The important thing for BBO to obtain substantial conversion effectiveness. Limited emphasis of laser beam isn't suggested.
Hygroscopic crystal products deteriorate when they are not generally stored in sufficiently dry air (or possibly a dry purge gasoline). This is applicable e.g. to KDP and BBO, and in a lesser extent to LBO. It could be beneficial to help keep this type of crystal at a considerably elevated temperature, that makes it much easier to preserve it dry.
EKSMA Optics uses cookies to supply you with the ideal searching expertise. For those who continue to employ our providers, we will suppose which you agree to using these cookies.
Remember to Observe that We now have a buffer crafted in between the desired injury thresholds on the web and the checks which We've got performed, which accommodates variation concerning batches. On ask for, we can offer unique check details and also a tests certification.
A second concern would be that the team velocity mismatch concerning the next harmonic and elementary-frequency pulses will lead to 1 pulse lagging the other as the two propagate. This known as temporal wander-off and can take place even below optimal section-matched problems.
The team velocities of the basic and second harmonic pulses also are unique, even if phase-matched, plus the magnitude in the group velocity mismatch is determined by the crystal Houses as well as optical frequencies during the pulses.
If you do not discover the ideal products and solutions over, it's possible you'll let's know your needs or programs in the shape beneath. Our gross sales or specialized personnel will get back to you at the earliest opportunity.
NCPM takes place in the event the input beam propagates at an angle other than zero or ninety levels worrying one of the important axes, like the Z-axis. Its polarization is parallel to that more info axis, including Z-polarized.
Moreover, BBO crystals are also noted for their higher nonlinear coefficient, which allows them to successfully transform the frequency of light.
The 266nm generation refers back to the manufacture of ultraviolet light-weight by using a wavelength of 266 nanometers.
flux-developed KTP and RTP with its significant nonlinearity, also in variants with substantial gray monitoring resistance
