The TSSG method is a relatively new approach which includes attained reputation for its capability to generate large-top quality crystals with lower defect density.
Pulsed good point out UV lasers have already been investigated for creating the ultrashort wavelength deep ultraviolet mild that presently originates from excimer lasers, as Employed in photolithography of semiconductor chips.
These characteristics lower the alignment sensitivity of the optical technique and make certain much better beam propagation. The much less stringent alignment demands and much better beam top quality conferred by these functions usually idea the scale in favor of LBO Crystals above other nonlinear optical crystals.
The flux strategy permits the creation of substantial LBO crystals with minimal defect density and high optical top quality. The use of a flux may also help to reduce impurities and defects while in the crystal, bringing about improved crystal good quality.
five mm to minimize group velocity mismatch and are perfect for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The significant and noncritical phase matching LBO crystals are perfect for next or third harmonic era of Nd:YAG and Yb:doped lasers.
Procedure of nonlinear crystals at temperatures below area temperature (to realize stage matching) is mostly problematic, as it might cause condensation of water on the crystal surfaces In the event the encompassing air is just not really dry.
SHG and THG for middle and substantial power Nd: lasers at 1064 nm for healthcare, industrial and army applications
UV lasers excel at marking. Resources which have been or else transparent, together with frequent glass, lenses, and prisms, a variety of sorts of plastics and natural and inorganic products is usually specifically marked with frequency tripled light.
In several conditions, a nonlinear crystal utilized for nonlinear frequency conversion has a really very long lifetime, and that is lengthier than that of The full laser method. The crystal substance is basically not modified throughout Procedure. Having said that, a decreased crystal life time can come about less than various situations:
Shorter wavelength light-weight with greater Power pulses delivers improved precision and more compact place sizing than industrial energy neodymium or CO2 lasers, As a result reaching finer resolution and precision.
When stacked up versus other nonlinear optical crystals, LBO Crystals unmistakably maintain their ground. Their wide transparency array is a particular trait that surpasses most other crystals in the sphere.
PL spectroscopy is a robust system for characterizing the luminescent Houses of LBO nonlinear crystals. PL spectroscopy includes shining a laser beam onto the crystal and measuring the emitted light at different wavelengths.
For buyer convenience and protection of crystals, standard 1" anodized aluminum (Al) mounts click here could be available on ask for. The mounted crystals might be even further mounted in a traditional one" mirror mount to be angle tuned for stage matching (
Crystal progress is actually a critical move in the manufacture of higher-high quality LBO nonlinear crystals. The choice of crystal progress method can noticeably impression the crystal good quality and optical Houses on the ensuing crystal. The Czochralski, flux, and TSSG methods are the most often utilized approaches for your manufacture of LBO nonlinear crystals, Just about every with its advantages and drawbacks.
