The substantial destruction threshold of BBO crystals is particularly vital in environments where superior-depth lasers are definitely the norm. Conventional resources could possibly falter, degrade, as well as break underneath such intensities.
A1: Certainly, BBO crystals Have a very higher injury threshold, making them appropriate for high-ability laser devices. Their ability to resist significant laser intensities without struggling from optical destruction will make them a wonderful option for frequency conversion in high-electrical power lasers.
The situation from the environmentally friendly curve is dependent upon θ. In cases like this, the angle θ has actually been tuned to deliver a refractive index for 515 nm gentle that matches the refractive index for 1030 nm light-weight. This tuning angle is hence optimized for Type-I SHG period matching plus a essential-frequency input beam of 1030 nm.
Nonetheless, to fully utilize the probable of BBO crystals, it is actually crucial to understand their Homes and the way to cope with and shop them adequately. These crystals demand watchful dealing with to forestall harm to their surfaces and may be saved in a dry, interesting area to maintain their optical overall performance.
Any contamination can degrade the optical effectiveness with the crystal and likely induce hurt underneath higher laser electricity. When storing BBO crystals, they need to be placed within a protecting scenario to prevent physical destruction and dust accumulation.
Be sure to Be aware that we have a buffer developed in between the specified destruction thresholds on the web and the exams which We've got done, which accommodates variation among batches. Upon request, we can offer particular person exam info along with a screening certification.
Section matching drastically increases the conversion performance and may be required to acquire sufficient frequency-doubled gentle for programs, but second harmonic technology (SHG) will come about regardless of whether section matching is just not performed. The influence of section matching around the output intensity of SHG light (I2ω) is illustrated in Determine sixteen.
Nevertheless, when BBO crystals can operate at home temperature, Excessive temperatures really should still be prevented as they're able to have an affect on the crystal’s section-matching circumstances and likely trigger damage.
Pumped from the fourth harmonic of a Nd:YAG laser (at 266nm), a tunable OPO with sign wavelength selection in between 422nm and 477nm has more info been observed by angle-tuning a type I BBO crystal. Pumped by a 1mJ, 80fs Dye laser at 615nm, the OPA with two BBO crystals yields greater than 50µJ (utmost a hundred thirtyµJ),
The period velocity is the rate at which the sphere provider, i.e. the sine wave, travels in a material. The speed at which a pulse envelope travels in a fabric is called the group velocity and defines the pace of the Electrical power packet comprising the optical pulse touring by the material.
Each facet of BBO, from its atomic construction to its broad application spectrum, underscores its pivotal position in modern-day science and know-how.
When evaluating an LIDT specified for your pulsed laser to your laser, it is critical to understand the subsequent:
The 266nm generation refers to the creation of ultraviolet gentle by using a wavelength of 266 nanometers.
BBO’s flexibility really shines when just one considers the breadth of its applications. It’s not merely confined to one area of interest of photonics but stretches throughout numerous domains. Get frequency doubling, By way of example. In this method, photons Along with the similar frequency Blend inside the crystal to supply new photons with double the frequency of the first.
