BIBO Crystal Fundamentals Explained
BIBO Crystal Fundamentals Explained
Blog Article
The susceptibility to moisture of BiBO is quite reduced. Having said that, users are encouraged to provide dry situations for equally use and storage of BiBO to lengthen the life time. Drinking water condensation on crystal surfaces ought to be Completely avoided Anytime.
Laser processing and product handling: In the sector of laser processing and material handling, the significant power ability of BIBO crystals helps make them a crucial ingredient while in the manufacture of large Power density laser beams.
five mm to reduce team velocity mismatch and are ideal for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The vital and noncritical period matching LBO crystals are perfect for next or third harmonic era of Nd:YAG and Yb:doped lasers.
The quantity of the solvent may be altered for a variety of crystal dimension so the lens tissue is retained damp for the whole drag but there's not any visible trace of solvent around the crystal floor after the drag is finished. Inspect the area and repeat if needed, but only use each sheet of lens tissue at the time.
Also, it could be extremely fascinating to use a crystal material which can be critically period-matched at area temperature due to the fact noncritical section matching typically requires the Procedure on the crystal in a temperature-stabilized crystal oven. On the other hand, the feasibility of vital phase matching may very well be offered only for sufficiently significant peak powers.
Dust and stains on crystal surfaces could cause scattering/loss of click here light and may even react with light-weight to break optical surfaces in a significant incident laser ability.
The selection of the best suited crystal material to get a specified software is frequently much from trivial; it really should include the thought of numerous factors. Such as, a higher nonlinearity for frequency conversion of ultrashort pulses isn't going to assistance In the event the conversation size is strongly minimal by a large team velocity mismatch and the low damage threshold limits the relevant optical intensities.
Scientific study and advancement: BIBO crystals also Engage in a significant job in scientific research and development. Its fantastic nonlinear optical general performance presents new applications and options for ultrafast phenomenon investigation, sturdy subject physics, biomedical imaging and also other fields
In the situation of ultrashort pulses the superior team velocity mismatch enforces the usage of a shorter crystal, which demands substantial optical intensities for the supplied conversion effectiveness.
A variety of Houses of a nonlinear crystal is usually significant for an application e.g. in nonlinear frequency conversion:
In many circumstances, a nonlinear crystal used for nonlinear frequency conversion has a very lengthy lifetime, which can be longer than that of The complete laser process. The crystal materials is essentially not modified during Procedure. On the other hand, a minimized crystal life time can take place under different situation:
This combination can make BIBO crystal exceptionally fitted to harnessing the phenomenon of second harmonic era (SHG) in just reliable-point out lasers and laser diodes.
linear absorption, which may result in heating at higher optical power amounts, so the period matching is disturbed, and thermal lensing may possibly manifest
flux-developed KTP and RTP with its higher nonlinearity, also in variants with high grey monitoring resistance
