The calculation above assumes a uniform beam intensity profile. You will need to now take into account hotspots within the beam or other non-uniform intensity profiles and about work out a most energy density.
The 266nm wavelength delivers distinct interactions that other wavelengths can’t, rendering it indispensable for detecting and researching sure compounds.
Hi there, thank you for calling 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 might be produced by reaching out to us at techsupport@thorlabs.com
Nonetheless, it’s crucial to Notice that whilst BBO crystals can cope with high power, they should nonetheless be made use of within just their specified energy array to stop opportunity hurt and make certain best functionality.
No matter if it’s in the event of a lot more productive lasers, the exploration of quantum phenomena, or the creation of latest optical devices, BBO crystals will undoubtedly continue on to Engage in a pivotal position.
The performance on the SHG approach decreases considerably as the fundamental beam diverges from its aim, Because the pulse Vitality is distributed throughout a bigger beam cross part.
Even though the check outcomes are only representative of one coating operate, Thorlabs specifies hurt threshold values that account for coating variances.
This precision permits the fabrication of intricate structures and patterns on several products, from metals to biological tissues. It’s not almost earning smaller click here sized objects; it’s about developing them with an unparalleled standard of element.
One example is, think about a elementary pulse propagating about a given crystal thickness. Once the temporal walk-off is larger than the length of the elemental pulse, this pulse will even have a spectral bandwidth that significantly exceeds the spectral width with the reference pulse. A common rule for limiting the harmful consequences connected to both physical results is to select a crystal thickness that boundaries the basic and second harmonic temporal walk-off to no more than the duration of the fundamental pulse.
With proper care and managing, BBO crystals can previous for quite some time. Nonetheless, their lifespan is usually shortened by variables such as substantial temperature, humidity, and Actual physical destruction. BBO crystals are strong and durable, but Like all optical part, they might degrade with time if not adequately cared for.
The raw supplies, usually a combination of barium carbonate and boric acid, are positioned within a platinum crucible and heated right up until they melt. The temperature is then progressively diminished, making it possible for the BBO crystal to kind above a number of months. The crystal is then extracted, Minimize into the desired condition, and polished to realize a higher-excellent optical surface area.
Of course, BBO crystals may be tailored In keeping with particular demands. This includes customized measurements, designs, and coatings. Having said that, customization may well impact the crystal’s Houses and functionality, so it ought to be done by an experienced. Tailor made dimensions and shapes could be Minimize from a bigger BBO crystal to suit specific programs.
Their supremacy Within this area is not merely by chance, but a result of their intrinsic and meticulously crafted Qualities.
This post dives deep into the benefits and special Houses of BBO crystal and its paramount value in economical frequency doubling and harmonics technology at 266nm.
