A1: Sure, BBO crystals Possess a higher harm threshold, producing them well suited for superior-energy laser methods. Their capability to withstand higher laser intensities without the need of struggling from optical problems would make them an outstanding choice for frequency conversion in higher-electrical power lasers.

Hi, thanks 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 is often created by achieving out to us at [email protected]

Nonetheless, to totally use the possible of BBO crystals, it is actually crucial to understand their Attributes and the way to tackle and store them appropriately. These crystals involve thorough handling to circumvent damage to their surfaces and should be saved in a dry, interesting place to take care of their optical general performance.

Figure 23: This diagram illustrates a beam's focal region within a uniaxial birefringent content. Straight lines, representing rays, are drawn from the Middle of the beam midsection. As being the beam diverges in the beam waist, the Vitality while in the beam is distributed in excess of a larger cross sectional area.

Thorlabs expresses LIDT for CW lasers being a linear ability density calculated in W/cm. Within this regime, the LIDT specified for a linear power density might be placed on any beam diameter; just one doesn't ought to compute an altered LIDT to adjust for modifications in spot dimensions, as shown by the graph to the right. Ordinary linear electrical power density could be calculated utilizing the equation down below. 

Occasionally, the mismatch is often compact. Such as, every time a β-BBO crystal is accustomed to frequency double 1550 nm gentle and provide 775 nm gentle, the group velocity mismatch is only some femtoseconds for every millimeter.

These Qualities make BBO crystals really fascinating in numerous purposes, from laser frequency conversion to electro-optic modulation. Their huge transparency vary makes it possible for them to work using a wide range of laser wavelengths, whilst their higher damage threshold makes certain they can handle superior-electrical power laser beams with out degradation.

BBO crystals ought to be dealt with with care to prevent scratching or harmful their surfaces. They ought to be saved inside of a dry, amazing spot and held away from direct sunlight. Normal cleaning using a soft cloth or air click here blower is recommended to take care of their optical overall performance. When handling BBO crystals, it’s essential to use gloves to forestall oils from your skin from contaminating the crystal floor.

A5: Of course, BBO crystals have superb thermal steadiness and can manage their Houses at home temperature. Which means that they are often Employed in an array of environments with no necessitating special temperature control.

Each individual side of BBO, from its atomic construction to its broad application spectrum, underscores its pivotal part in modern science and technological know-how.

For beams that has a superior PRF both equally the standard and peak powers should be as compared to the equivalent CW electrical power. Additionally, for really clear components, There's little to no drop from the LIDT with escalating PRF.

The duration from the crystal is an important parameter to consider when optimizing the SHG process for that parameters of certain enter pulses. Absent stage-matching and temporal walk-off results, the SHG output raises exponentially with crystal duration. The goal when finding an SHG crystal is usually to equilibrium the crystal duration with the limitations determined by the fundamental pulse. Decreasing the crystal thickness minimizes effects related to each stage-matching bandwidth restrictions and temporal walk-off, that are immediately relevant.

This is especially vital in industries like semiconductors and micro-electromechanical techniques (MEMS), where even a minimal error can render a part ineffective or cause important losses. With BBO’s 266nm era, industries can accomplish better accuracy and reliability inside their fabrication procedures, driving innovation and merchandise quality to new heights.
