A: Certainly, BBO crystals exhibit extraordinary thermal balance, producing them ideal for purposes with various temperatures.
Howdy, thank you for contacting Thorlabs. The wavelength ranges of your antireflective coatings on these β-BBO crystals align Together with the respective wavelength bands that these crystals are optimized for. Requests for customizations is usually created by reaching out to us at [email protected]
The weight from the solvent will induce the lens tissue to come into connection with the crystal area. Slowly but steadily drag the moist lens tissue throughout the crystal surface becoming cautious not to lift the lens tissue off on the floor. Continue on dragging the lens tissue right until it can be off of the floor.
To be able to use the specified CW destruction threshold of an optic, it is necessary to understand the next:
The 2nd harmonic gentle is then polarized parallel on the airplane. Angle tuning adjusts θ and is also done by rotating the crystal throughout the Y-axis.
BBO crystals have two refractive indices: ne for extraordinary rays and no for regular rays. The distinction between ne and no relies on the wavelength of sunshine plus the crystal’s temperature.
The stage velocity is the speed at which the sphere provider, i.e. the sine wave, travels in a material. The rate at which a pulse envelope travels in a material is known as the team velocity and defines the velocity of your Electricity packet comprising the optical pulse touring by way of the fabric.
BBO crystals are utilized within a big selection of programs because of their Extraordinary optical Qualities. They are commonly used in laser systems for frequency conversion, which include next, third, and fourth harmonic generation. This permits for your manufacture of laser mild at distinct wavelengths from an individual input wavelength.
) to blow off dust along with other loose contaminants to start with. If a dry nitrogen line is available during the lab, an air gun can even be employed to blow away dust particles. Blow off the area Carefully. Will not blow off the crystal alone from your hand!
The Vitality density within your beam need to click here be calculated concerning J/cm2. The graph to the correct demonstrates why expressing the LIDT as an Strength density provides the most beneficial metric for brief pulse resources. With this routine, the LIDT offered as an energy density may be placed on any beam diameter; a person doesn't should compute an altered LIDT to regulate for variations in location measurement.
Moreover, the structural and compositional characteristics of BBO present it with exceptional thermal security and resistance versus environmental troubles.
A number of Homes of the nonlinear crystal may be important for an software e.g. in nonlinear frequency conversion:
Therefore, the second harmonic pulse spectrum, demonstrated on the appropriate, has a spectral width approximately the same as the ideal situation. Preferably, every single frequency in the fundamental pulse spectrum could be concurrently phase matched.
This can make them highly sturdy and resilient, further more improving their suitability for difficult optical applications.
