The two broad-bandwidth pulses and temporal stroll-off cause a reduction during the conversion effectiveness, together with worsen the optical quality of the next harmonic pulses. The suitable crystal thickness need to be picked out to attenuate equally results.
Nonetheless, it’s crucial to Be aware that though BBO crystals can transmit UV light-weight, they should be dealt with with treatment when Utilized in UV programs to avoid opportunity harm to the crystal and make certain safety.
A1: Certainly, BBO crystals Have a very superior injury threshold, generating them suited to high-electric power laser systems. Their ability to withstand significant laser intensities with no suffering from optical destruction helps make them a fantastic option for frequency conversion in substantial-electricity lasers.
The Z-axis is parallel to the optical axis of your crystal in addition to is additionally known as the wonderful axis. The X- and Y-axes are parallel to your optical axis and therefore are known as typical axes.
Immediately after extraction, the BBO crystals are then Minimize into the desired sizes and shapes. This reducing procedure is executed with precision devices to make sure that the crystals are Minimize properly and cleanly.
If the crystal surfaces remain “soiled�?just after the above cleaning strategies, the surfaces might have been harmed. You should Call us for rework with the crystals.
The phase velocity is the speed at which the sector copyright, i.e. the sine wave, travels in a material. The rate at which a pulse envelope travels in a material is known as the team velocity and defines the pace in the Electricity packet comprising the optical pulse touring by way of the material.
The length on the crystal is a vital parameter to consider when optimizing the SHG method for the parameters of certain enter pulses. Absent phase-matching and temporal walk-off results, the SHG output boosts exponentially with crystal duration. The intention when picking an SHG crystal is to balance the crystal size with the limitations determined by the fundamental pulse. Lowering the crystal thickness lowers outcomes relevant to both of those stage-matching bandwidth constraints and temporal stroll-off, which might be directly relevant.
In quasi-section matching, the crystal content is “poled�?to obtain up and down domains to counteract the stage-mismatch of the fabric, exactly where the poling period of time is specific on the wavelengths of conversation.
GWU-Lasertechnik provides all conventional nonlinear crystals like LBO, BBO and KTP with a wide selection of more info requirements. Beside the nicely-recognized elements, modern crystals like CLBO or BiBO with fantastic properties for e. g. deep-UV generation or superior-electric power ultrashort pulse lasers can be found. Irrespective of if particular person pieces for R & D needs are needed or Expense-economical quantities in little, medium or substantial batches with in-time supply for that manufacturing line are wanted: GWU’s dedicated services helps you to discover the best core factors on your application.
Moreover, the structural and compositional attributes of BBO give it with impressive thermal security and resistance from environmental challenges.
The placement from the inexperienced curve relies on θ. In this case, the angle θ has become tuned to deliver a refractive index for 515 nm mild that matches the refractive index for 1030 nm mild. This tuning angle is as a result optimized for Style-I SHG period matching and a elementary-frequency input beam of 1030 nm.
The 266nm generation refers to the production of ultraviolet mild that has a wavelength of 266 nanometers.
This tends to make them hugely strong and resilient, additional improving their suitability for demanding optical purposes.
