This post dives deep into the advantages and special Houses of BBO crystal and its paramount great importance in successful frequency doubling and harmonics technology at 266nm.
In lots of scenarios, a nonlinear crystal useful for nonlinear frequency conversion has a very prolonged life span, that's longer than that of The complete laser system. The crystal substance is actually not modified during Procedure. Having said that, a decreased crystal life span can arise under many instances:
Optical transmission (OT): We employ OT to measure the optical passage spectrum of our merchandise above their openness array. We warranty our items are devoid of absorption bands or scattering losses as a consequence of pollutants or complications.
The Z-axis is parallel for the optical axis of the crystal and also is additionally known as the great axis. The X- and Y-axes are parallel to the optical axis and therefore are termed frequent axes.
The 2nd harmonic gentle is then polarized parallel into the airplane. Angle tuning adjusts θ and is executed by rotating the crystal across the Y-axis.
This kind of resilience makes sure that its nonlinear Attributes usually are not simply compromised, making it a favorite in environments the place consistency and dependability are paramount.
The second harmonic frequency wave is created as a rare wave, that's polarized orthogonal to the fundamental-frequency common wave.
g. 20 μm. The team velocity mismatch inside the thicker substrate content might not matter, given that the nonlinear interaction normally takes put only in the thin crystal. The substrate only serves to mechanically stabilize the thin nonlinear crystal.
This precision permits the fabrication of intricate buildings and designs on numerous materials, from metals to Organic tissues. It’s not nearly making smaller objects; it’s about building them with the unparalleled degree of element.
GWU-Lasertechnik provides all regular nonlinear crystals like LBO, BBO and KTP that has a broad a number of specifications. Beside the well-established resources, revolutionary crystals like CLBO or BiBO with fantastic properties for e. g. deep-UV generation or large-ability ultrashort pulse lasers are offered. It does not matter if person items for R & D needs are demanded or Expense-successful figures in small, medium or massive batches with in-time shipping and delivery for the output line are necessary: GWU’s devoted support really helps to discover the most effective Main components on your software.
These crystals are exceptional thanks to their power to change the frequency of light passing by way of them, a residence that is very wanted in different fields including laser engineering and quantum physics. The versatility of BBO crystals will make them a vital ingredient in lots of Innovative optical techniques.
Pulsed lasers with superior pulse repetition frequencies (PRF) might behave equally to CW beams. Unfortunately, this is highly dependent on variables which include absorption and thermal diffusivity, so there isn't a reliable approach for analyzing any time a high PRF laser will injury an optic because of thermal results.

The length in the SHG crystal significantly impacts the spectral width with the reference pulse, or alternatively the bandwidth of the SHG filter.
