A Simple Key For BBO Crystal Unveiled

Sometimes, the mismatch is often tiny. As an example, each time a β-BBO crystal is used to frequency double 1550 nm light-weight and provide 775 nm mild, the team velocity mismatch is only a few femtoseconds for each millimeter.
In several scenarios, a nonlinear crystal utilized for nonlinear frequency conversion has an extremely extended lifetime, that is longer than that of The entire laser method. The crystal product is essentially not modified during Procedure. Even so, a reduced crystal lifetime can arise underneath different instances:
This type of ability is a must have in predicaments where by a specific gentle frequency is necessary, however the supply doesn’t Normally supply it. By making use of BBO’s Homes, researchers and engineers can efficiently “tune�?their gentle sources to ideal frequencies.
To be able to use the desired CW damage threshold of the optic, it is necessary to find out the subsequent:
Just after extraction, the BBO crystals are then Slice into the specified shapes and sizes. This cutting approach is carried out with precision instruments in order that the crystals are Lower precisely and cleanly.
Be sure to decide on your shipping and delivery region to check out essentially the most accurate inventory facts, and to find out the proper Edmund Optics profits office on your order.

When 1 of those β-BBO Crystals is mounted while in the RSP1 mount, the crystal is going to be centered about the eight-32 (M4) gap while in the mount's foundation with no want for spacers.
This calculation assumes a uniform beam intensity profile. You will need to now regulate this energy density to account for hotspots or other nonuniform intensity profiles and roughly calculate a utmost Electrical power density. For reference a Gaussian beam commonly contains a maximum Power density that is certainly twice that of your 1/e2 beam.
For instance, anti-reflective coatings is often applied to cut down gentle reduction because of reflection, though protective coatings can be utilized to increase the crystal’s resistance to environmental components. Customization allows for exceptional effectiveness in particular purposes.
Moreover, the structural and compositional attributes of BBO present it with outstanding thermal balance and resistance versus environmental difficulties.
The pole is gradually brought up although revolving at a regular pace. This triggers a skinny thaw layer to improve the seed crystal, developing a spherical boule.
Hence, the 2nd harmonic pulse spectrum, proven on the right, provides a spectral width roughly similar to the ideal case. Ideally, each individual frequency in the basic pulse spectrum could well be simultaneously stage matched.
Humidity can cause h2o absorption within the crystal floor, which might degrade its optical performance. The caliber of the incident mild, including its wavelength, depth, and polarization, could also have an effect on the overall performance of BBO crystals in click here many apps.
