A Simple Key For BBO Crystal Unveiled

These raw elements are cautiously measured and blended in exact proportions to make sure the best composition of the ensuing crystals.
Though the above process offers an excellent general guideline for LIDT values, remember to Speak to Tech Assistance In case your wavelength is different from the required LIDT wavelength. In the event your electricity density is a lot less than the altered LIDT in the optic, then the optic should really do the job in your software.
The temporal stroll-off on the slower pulse with respect for the speedier is often a considerable portion of the heartbeat length. This really is illustrated in Figure 22.
Now Review the maximum energy density to that that's specified as being the LIDT for your optic. If the optic was tested at a wavelength apart from your running wavelength, the destruction threshold has to be scaled correctly [three].
, the angle among the light's propagation route as well as crystal's optic axis may be tuned so that the refractive index of a selected frequency (ω) in the fundamental input pulse accurately equals the refractive index of 2 times the input frequency (twoω). It is typical to improve stage matching circumstances for the frequency at approximately the center of the pulse's bandwidth.
Quite a few components can impact the overall performance of BBO crystals. These include temperature, humidity, and the standard of the incident gentle. Right managing and storage may help keep the crystal’s performance. Temperature can impact the section-matching ailments of BBO crystals, which in turn affects their efficiency in frequency conversion programs.
When an optic is damaged by a ongoing wave (CW) laser, it is generally mainly because of the melting with the surface on account of absorbing the laser's Strength or harm to the optical coating (antireflection) [1]. Pulsed lasers with pulse lengths extended than 1 µs is often addressed as CW lasers for LIDT discussions.
The team velocity plus the stage velocity usually are not equal, indicating the website sine wave of your copyright and also the envelope of the heart beat shift by optical media at distinctive speeds.
The spatial walk-off angle relies on the size with the beam and the crystal length. When the angle can be considerable, it is generally small, generally about the purchase of 10 mrad, and may be neglected.
Instead of decompose the SHG polarization into parts Ex and Ez, The sunshine is usually called a rare wave (E'e) using a refractive index, n'e. From the diagram on the best, n'e, which relies on θ, is indicated via the intersection in the conic section illustrated from the red ellipse Together with the XZ aircraft.
The four reduce figures illustrate which the group velocity hold off (temporal wander-off) raises since the pulses propagate via the material. The temporal walk-off is illustrated for distances Z0 via Z3, which can be indicated within the diagram at top.
Having said that, in lots of instances, the main difference in the fundamental and 2nd harmonic pulse velocities might cause just one pulse to significantly lag the opposite.
