The large injury threshold of BBO crystals is especially essential in environments wherever superior-depth lasers are definitely the norm. Traditional products may possibly falter, degrade, or even crack beneath these types of intensities.
β-BBO Crystal—a widely made use of nonlinear crystal for frequency conversion within the ultraviolet, visible and around-infrared
Hello there, thanks for contacting Thorlabs. The wavelength ranges in the antireflective coatings on these β-BBO crystals align with the respective wavelength bands that these crystals are optimized for. Requests for customizations can be created by reaching out to us at [email protected]
This enhancement in clarity can result in early analysis and timely intervention, most likely preserving life and strengthening patient results.
Numerous things can influence the performance of BBO crystals. These include things like temperature, humidity, and the caliber of the incident mild. Correct handling and storage may help sustain the crystal’s performance. Temperature can impact the period-matching conditions of BBO crystals, which subsequently has an effect on their effectiveness in frequency conversion programs.
The efficiency on the SHG process decreases substantially as the elemental beam diverges from its emphasis, Because the pulse Strength is distributed throughout a bigger beam cross area.
Sometimes, the mismatch is often modest. For example, every time a β-BBO crystal is accustomed to frequency double 1550 nm light-weight and supply 775 nm light-weight, the group velocity mismatch is just a few femtoseconds per millimeter.
When an optic is destroyed by a continuous wave (CW) laser, it is normally mainly because of the melting in the floor on account of absorbing the laser's Power or damage to the optical coating (antireflection) [one]. Pulsed lasers with pulse lengths for a longer period than 1 µs could be dealt with as CW lasers for LIDT discussions.
This property sets it other than linear optical resources that don’t change the frequency of light passing through them. This kind of distinguishing attribute types the foundation for a myriad of applications that BBO can serve.
Hello, I was thinking if It can be achievable in your case to create a BBO crystal having a custom made coating at 532nm basic and 266nm next harmonic technology. Most effective, Ben
The group velocity along with the section velocity are usually not equivalent, indicating the sine wave of the provider as well as the envelope of the pulse go by way of optical media at distinct speeds.
The angular articles in the resultant SHG pulse, or beam, during the dimension on the angular filter is lowered from a perfect scenario. In the perpendicular dimension, the SHG beam preserves the angular content material of your input beam, since there’s no angular filter in that dimension. A diverging beam with asymmetric NA’s, read more i.e. while in the horizontal and vertical dimensions, contributes to an elliptical beam.
Thermal fluctuations are a priority in lots of experimental and industrial setups. Yet, BBO crystals�?intrinsic thermal stability makes sure that they don’t just survive but thrive in these types of circumstances.
This text dives deep into the advantages and unique Attributes of BBO crystal and its paramount worth in productive frequency doubling and harmonics generation at 266nm.
