Crystals that happen to be non-critically section-matched inside a crystal oven might exhibit troubles when the crystal temperature is improved much too rapidly or also frequently. Specifically, anti-reflection coatings could be ruined due to unique thermal enlargement coefficients in the included products.
The issue that arises when working with ultrashort pulses for next harmonic era (SHG) is the fact that shorter pulses have more substantial bandwidths, but The perfect section-matched situation is often achieved for only an individual essential wavelength at any given time. Resulting from this, the caliber of the section match is often noticeably even worse toward the spectral edges of wide-bandwidth pulses.
five mm to minimize group velocity mismatch and are ideal for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The crucial and noncritical period matching LBO crystals are perfect for second or 3rd harmonic generation of Nd:YAG and Yb:doped lasers.
In the huge planet of nonlinear optical crystals, BBO crystals stick out as pioneers, especially in the realm of 266nm generation.
Broad openness selection: BBO crystals have a wide openness array from 189 nm to 3500 nm, masking ultraviolet, obvious, and close to-infrared locations. This enables BBO crystals for use for numerous laser sources with various wavelengths.
If the crystal surfaces remain “filthy�?following the above mentioned cleansing processes, the surfaces may have been damaged. Remember to contact us for rework with the crystals.

Nonlinear Crystals of either β-barium borate (BBO) or lithium triborate (LBO) are utilized for frequency conversion of laser resources. BBO crystals feature thicknesses from 0.2mm to 0.5mm 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 stage matching LBO crystals are perfect for second or 3rd harmonic generation of Nd:YAG and Yb:doped lasers.
BBO’s flexibility actually shines when just one considers the breadth of its purposes. It’s not only confined to one specialized niche of photonics but stretches across several domains. Consider frequency doubling, For illustration. In this method, photons with the similar frequency combine in the crystal to supply new photons with double the frequency of the initial.
It’s like having only one Notice and splitting it into two harmonious tones. This method may be more info crucial in various Sophisticated optical experiments and systems.
High nonlinear coefficients: BBO crystals have substantial nonlinear coefficients which make efficient frequency conversion processes with very low input electricity calls for probable.

GWU-Lasertechnik has in excess of 30 several years of practical experience in distributing laser crystals. Decide on GWU to take pleasure in our broad understanding and in-discipline experience!
Lastly, the cut crystals are polished into a smooth end. This sprucing procedure not only boosts the aesthetic visual appeal with the crystals but will also improves their optical properties by decreasing surface area imperfections.
