However, it might be very hard to compare the LIDT specification of the optic on your laser. There are multiple regimes through which a pulsed laser can harm an optic and this is predicated around the laser's pulse size. The highlighted columns inside the table underneath outline the relevant pulse lengths for our specified LIDT values.
The flexibility of BBO crystals to change the frequency of light has created them indispensable in laser know-how. They have got enabled the manufacture of a broad spectrum of light colours, considerably over and above what is straight accessible from offered laser resources.
A: Indeed, BBO crystals exhibit spectacular thermal security, creating them ideal for applications with various temperatures.
Lastly, the broad-angle tunability of BBOs facilitates customization like under no circumstances right before. With regards to the precise demands of an application, the crystal could be modified with precision, making certain that the output is always optimized.
Now Evaluate the maximum electric power density to that that's specified given that the LIDT with the optic. If the optic was analyzed at a wavelength besides your operating wavelength, the damage threshold need to be scaled correctly.
Physically, when the basic spectrum is nicely inside the reference pulse spectrum, the website SHG pulse depth profile could be the square of the elemental intensity profile, successfully truncating the length. This case is illustrated in Determine 20.
This type of capacity is invaluable in scenarios exactly where a certain light frequency is required, though the supply doesn’t Normally provide it. By employing BBO’s properties, scientists and engineers can correctly “tune�?their mild resources to desired frequencies.
Because the refractive index won't differ linearly with frequency in dispersive crystals like β-BBO, it can be impossible to optimally period match each and every frequency in the input pulse's spectral selection Using the corresponding 2nd harmonic frequency while in the generated pulse.
Therefore, the next harmonic pulse spectrum, proven on the proper, provides a spectral width about the same as The perfect scenario. Ideally, each and every frequency in the fundamental pulse spectrum would be at the same time period matched.
Each and every side of BBO, from its atomic framework to its broad software spectrum, underscores its pivotal part in modern science and know-how.
While in the large globe of nonlinear optical crystals, BBO crystals stand out as pioneers, specifically in the realm of 266nm era.
On the other hand, the nonlinear optical Attributes of the-BBO crystal is vanished because of the centric symmetry with its crystal construction. It's not at all encouraged to use for NLO processes.
Generation of deep ultraviolet radiation at 210 nm by Kind-I third harmonic generation is accomplished inside a set of BBO crystals with conversion effectiveness as superior as 36%.
