You'll want to think about the wavelength and ability of your respective laser resource and opt for a crystal which is transparent in the offered wavelength and can withstand the laser electric power. And finally, other components including the thermal stability, optical homogeneity, and nonlinear optical coefficient in the crystal also have to be deemed.
But LBO has greater transparency, a lot less flaws, and will not suffer from gray tracking. The result is larger electricity and life span ability. It's also more affordable than hydrothermal KTP, so it has begun to interchange KTP in the greater demanding apps.
The quantity of the solvent might be modified for many crystal dimensions Therefore the lens tissue is saved moist for the whole drag but there's not any noticeable trace of solvent about the crystal area once the drag is completed. Inspect the surface and repeat if required, but only use Every sheet of lens tissue as soon as.
five mm to minimize group velocity mismatch and are perfect for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The important and noncritical stage matching LBO crystals are perfect for next or third harmonic technology of Nd:YAG and Yb:doped lasers.
The characterization of LBO nonlinear crystals is important for knowledge their Attributes and optimizing their overall performance in different applications. This chapter discusses the different characterization procedures utilized for LBO nonlinear crystals.
X-ray diffraction is a strong approach for figuring out the crystal composition and orientation of LBO nonlinear crystals.
The Czochralski method allows for the manufacture of massive one crystals with great excellent, although the flux process can reduce impurities and defects during the crystal. The TSSG process presents specific Handle around crystal orientation and defect density, plus the hybrid approach brings together the benefits of the TSSG and Czochralski procedures.
Type II NCPM OPO pumped by a XeCl excimer laser at 308nm has obtained 16.five% conversion performance, and average tunable wavelength ranges is usually received with distinctive pumping resources and temperature tuning.
The nonlinear optical coefficients of LBO more info nonlinear crystals Participate in a crucial purpose in identifying the performance of frequency doubling as well as other nonlinear optical processes. A very powerful coefficient is the second-harmonic generation (SHG) coefficient, and that is chargeable for frequency doubling in LBO crystals.
However, if the applying requires, these crystals could also endure particular elevated pressure problems. It is often proposed to consult that has a crystal professional or seek advice from certain company suggestions to determine the optimal situations for your unique LBO Crystal and software.
Among the most widespread programs is frequency doubling, where LBO Crystals competently change the frequency of the large electrical power laser, effectively halving the wavelength and opening up a spectrum of alternatives for laser programs.
The most common approach for obtaining period-matching in LBO nonlinear crystals is angle tuning, exactly where the crystal is rotated to discover the best angle that satisfies the section-matching situation.
Crystal growth is actually a essential stage inside the production of significant-high-quality LBO nonlinear crystals. The selection of crystal advancement technique can considerably affect the crystal high-quality and optical Homes with the ensuing crystal. The Czochralski, flux, and TSSG approaches are definitely the most commonly employed strategies for your creation of LBO nonlinear crystals, Each and every with its advantages and drawbacks.
