The crystal axis is c. The Main ray is parallel towards the direction accustomed to evaluate the tuning angle (θ), which can be optimized through period matching. Conversion performance is optimized for rays parallel to your Main ray and worse for rays at more substantial angles (ψ) to your chief ray.
Nevertheless, in several scenarios, the real difference in the fundamental and next harmonic pulse velocities can result in a single pulse to substantially lag another.
A further Similarly intriguing application is optical parametric oscillation. In this, BBO permits the conversion of a photon into two photons with distinct frequencies, the sum of which equals the original photon’s frequency.
Rather than the reference pulse electric power spectrum comprising an apodization filter, inside the spatial area the filter could be in NA. The angular area apodization filter on the other hand, is just in a single-dimension outlined with the plane k and .
Any contamination can degrade the optical functionality from the crystal and possibly trigger problems beneath large laser electricity. When storing BBO crystals, they need to be placed inside of a protective situation to stop physical hurt and dirt accumulation.
Remember to Notice that We've a buffer crafted in between the specified harm thresholds on the internet and the exams which We've got finished, which accommodates variation between batches. On ask for, we can offer person take a look at facts along with a testing certificate.
Humidity could potentially cause h2o absorption about the crystal surface area, which could degrade its optical functionality. The standard of the incident gentle, which include its wavelength, intensity, and polarization, also can have an affect on the functionality of BBO crystals in numerous applications.
When an optic is destroyed by a ongoing wave (CW) laser, it is usually because of the melting with the surface on account of absorbing the laser's Electrical power or damage to the optical coating (antireflection) [1]. Pulsed lasers with pulse lengths longer than one µs can be addressed as CW lasers for LIDT conversations.
BBO crystals needs to be handled with treatment in order to avoid scratching or harming their surfaces. They ought to be saved in the dry, neat area and stored from immediate sunlight. Normal cleaning with a soft fabric or air blower is suggested to take care of their optical efficiency. When handling BBO crystals, it’s crucial that you use gloves to prevent oils in the skin from contaminating the crystal surface area.
The temporal stroll-off on the slower pulse with regard for the faster could be a substantial fraction of the heart beat period. This is illustrated in Determine 22.
Each and every side of BBO, from its atomic framework to its broad more info application spectrum, underscores its pivotal job in modern day science and technology.
Beta Barium Borate (BBO) crystals have taken the planet of photonics by storm. Probably the most impressive aspects of these crystals is their pioneering part in 266nm era.
The 266nm technology refers to the manufacture of ultraviolet light-weight with a wavelength of 266 nanometers.
