Normal cleansing and correct storage will help prolong the lifespan of BBO crystals. It’s also crucial that you prevent exposing the crystals to circumstances outside the house their specified working variety, as this can result in lasting damage.
Unfortunately, it could be very difficult to compare the LIDT specification of an optic to the laser. You'll find several regimes where a pulsed laser can problems an optic and this is predicated to the laser's pulse duration. The highlighted columns from the desk down below outline the related pulse lengths for our specified LIDT values.
Howdy, thanks for speaking to Thorlabs. The wavelength ranges in the antireflective coatings on these β-BBO crystals align Along with the respective wavelength bands that these crystals are optimized for. Requests for customizations may be created by achieving out to us at [email protected]
A: Of course, BBO crystals show amazing thermal steadiness, generating them suitable for programs with varying temperatures.
The phase-matching capabilities of BBO crystals ought to have Particular mention. Within the intricate dance of photons, wherever conversion from one wavelength to a different is usually wished-for, the phase-matching supplied by BBO makes certain that Electrical power losses are negligible.
Negative uniaxial α-BBO crystal is a superb birefringent crystal, suitable for the manufacture of polarizer, polarization beam displacer, time hold off compensator plate as well as other birefringent device, especially for UV and high electric power laser.
The spatial walk-off angle depends upon the size of the beam along with the crystal size. Even though the angle is usually major, it is usually modest, ordinarily to the purchase of ten mrad, and may be neglected.
As illustrated in the next table, the shorter the crystal, the broader the reference pulse spectrum. The table below assumes a elementary Middle wavelength in check here the in close proximity to-IR.
Since the refractive index would not vary linearly with frequency in dispersive crystals like β-BBO, it can be not possible to optimally phase match each and every frequency while in the enter pulse's spectral range Along with the corresponding second harmonic frequency within the produced pulse.
It’s like getting an individual note and splitting it into two harmonious tones. This process could be very important in a lot of Sophisticated optical experiments and systems.
The team velocity as well as phase velocity are certainly not equal, which means the sine wave of your copyright plus the envelope of the heart beat shift through optical media at different speeds.
This attribute interprets to lessened have to have for substantial thermal administration devices, yet again accentuating Price tag personal savings and program simplicity.
When an enter pulse's spectral vary is equivalent to or narrower compared to reference pulse, the created second harmonic pulse includes a period that may be shorter by an element of 1/√2 plus a spectral width that is broader by a factor of √two.
This is particularly essential in Organic and professional medical investigate wherever certain compounds or cells are tagged with fluorescent markers. The 266nm mild can excite these markers, creating them stand out clearly in opposition to a history, thereby facilitating detailed Examination.
