Sadly, it may be very difficult to compare the LIDT specification of an optic towards your laser. You will find numerous regimes where a pulsed laser can injury an optic which is predicated to the laser's pulse length. The highlighted columns in the table down below outline the related pulse lengths for our specified LIDT values.
The posture in the inexperienced curve relies on θ. In such a case, the angle θ is tuned to supply a refractive index for 515 nm light that matches the refractive index for 1030 nm light. This tuning angle is as a result optimized for Kind-I SHG stage matching as well as a basic-frequency input beam of 1030 nm.
A: A high problems threshold makes sure the crystal can deal with far more electrical power without having degrading, resulting in more time lifespan and regular efficiency.
From the ray-model perspective, the propagation path defines the orientation with the central (Main) ray in Figure 23. The SHG procedure is affected via the selection of angles over which incident gentle propagates, mainly because mild that's not parallel to your chief ray has reduced section-matching relative on the chief ray.
The efficiency in the SHG procedure decreases considerably as the elemental beam diverges from its concentration, For the reason that pulse energy is distributed across a bigger beam cross segment.
Even though the check outcomes are only agent of one coating run, Thorlabs specifies destruction threshold values that account for coating variances.
a-BBO crystals having a wedge angle (α) may be customized fabricated with the specified orientation of the optical axis. A paired or these kinds of prisms Together with the optical axes orthogonal to each other can be used to repeatedly alter the stage change or time hold off among two orthogonally polarized pulses.
BBO crystals may be ordered from a variety of suppliers specializing in optical resources. It’s important to go with a reputable supplier to guarantee the quality of the crystals.
Hi, I was pondering if It is possible for yourself to make a BBO crystal by using a customized coating at 532nm essential and 266nm 2nd harmonic generation. Most effective, Ben
Both of those broad-bandwidth pulses and temporal stroll-off bring about a reduction from the conversion performance, along click here with worsen the optical top quality of the second harmonic pulses. The appropriate crystal thickness need to be picked out to minimize the two results.
Because the dynamics of this process are really subject matter to experimental parameters, it's tough to arbitrarily predict the specific outcomes on the second harmonic pulse. These consequences can include things like back again conversion, in which next harmonic mild is transformed back again to fundamental gentle, and spectral narrowing from the SHG pulse.
A advised guideline for focusing femtosecond laser pulses right into a nonlinear crystal is to maintain a Rayleigh range that may be no less than numerous times extended as opposed to length with the SHG crystal. This minimizes the chance of harming the crystal, together with minimizes the destructive results of spatial section mismatch and spatial (Poynting vector) walk-off.
