BIBO crystal (bismuth triborate) is a relatively novel nonlinear product when compared with BBO and LBO crystals. BIBO crystal surpasses BBO when it comes to its successful nonlinearity, even though also providing a broader bandgap in comparison to KTP crystal.
Inertness to Moisture: BIBO crystal is inert to dampness, which implies it doesn't degrade or get rid of its optical Houses when subjected to humidity. This helps make BIBO a far more secure and reliable option for optical programs in various environments.
5 mm to reduce team velocity mismatch and are ideal for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The critical and noncritical section matching LBO crystals are perfect for second or third harmonic era of Nd:YAG and Yb:doped lasers.
Ordinarily, the crystal content ought to have a significant optical transparency for all wavelengths included �?as an example, for pump, sign and idler within an optical parametric amplifier.
Also, it might be very desirable to implement a crystal material which may be critically stage-matched at space temperature for the reason that noncritical phase matching usually consists of the Procedure of the crystal within a temperature-stabilized crystal oven. On the other hand, the feasibility of vital period matching might be provided only for adequately superior peak powers.
Dust and stains on crystal surfaces may cause scattering/decline of light and may even react with light to damage optical surfaces in a large incident laser energy.
At this time, as a kind of fantastic nonlinear next harmonic crystal, it can be employed to make large performance crystal of green or blue laser.
Operation of nonlinear crystals at temperatures down below space temperature (to obtain phase matching) is usually problematic, as it could lead to condensation of water to the crystal surfaces if the surrounding air is just not incredibly dry.
In summary, BIBO crystal is really a promising nonlinear optical content with Fantastic Attributes which make it suitable for a wide range of optical applications.
Extreme optical intensities throughout Procedure may possibly immediately destruction a crystal. Sad to say, nonlinear crystals usually should be operated not much from their optical destruction threshold to realize a sufficiently significant conversion efficiency. This suggests a trade-off involving conversion efficiency and crystal life span.
Non-linear Optical (NLO) crystals offer an enormously versatile Resolution for building new wavelengths from present, off-the-shelf laser sources. The optical wavelength spectrum is utilized by a considerable and frequently growing variety of applications, from manufacturing of healthcare lasers, quantum networking & computing by means of to environmental sensing along with several Other folks.
GWU-Lasertechnik gives all typical nonlinear crystals like LBO, BBO and KTP having a broad range of technical specs. Beside the check here nicely-proven elements, innovative crystals like CLBO or BiBO with excellent Homes for e. g. deep-UV era or significant-ability ultrashort pulse lasers are available. Regardless of if person pieces for R & D reasons are necessary or Expense-effective numbers in small, medium or significant batches with in-time supply to the manufacturing line are required: GWU’s focused provider helps to locate the greatest Main parts for the software.
linear absorption, that may trigger heating at significant optical power amounts, so the period matching is disturbed, and thermal lensing may perhaps happen
Because the 2nd harmonic (SHG) may be greatly used to crank out coherent visible gentle and ultraviolet radiation, people concentrate to it, but the normal nonlinear crystals like KDP, LBO, KTP, B-BBO even have lots of shortcomings. BIBO crystal is a different variety of nonlinear crystal. In contrast with KDP crystal, it would make up for the disadvantage that KDP crystal can increase in substantial size but dissolve in water.
