Inertness to Humidity: BIBO crystal is inert to moisture, meaning it does not degrade or get rid of its optical properties when exposed to humidity. This will make BIBO a more stable and trusted option for optical programs in many environments.
If the crystal surfaces remain “filthy�?after the above cleansing methods, the surfaces might need been damaged. Remember to Get hold of us for rework of your crystals.

The level of the solvent might be altered for several crystal measurement Therefore the lens tissue is kept moist for the entire drag but there is not any obvious trace of solvent to the crystal surface area once the drag is finished. Inspect the floor and repeat if necessary, but only use each sheet of lens tissue the moment.
Also, it can be really fascinating to implement a crystal materials which can be critically section-matched at place temperature mainly because noncritical phase matching often involves the Procedure from the crystal inside of a temperature-stabilized crystal oven. Having said that, the feasibility of critical stage matching may very well be provided just for adequately higher peak powers.
Dust and stains on crystal surfaces might cause scattering/decline of light and may even respond with mild to break optical surfaces in a higher incident laser electrical power.
The choice with the most fitted crystal content for just a provided software is commonly far from trivial; it must require the thing to consider of numerous areas. For instance, a high nonlinearity for frequency conversion of ultrashort pulses doesn't enable In case the conversation size is strongly constrained by a substantial group velocity mismatch and also the reduced damage threshold restrictions the applicable optical intensities.
And is especially advantageous for building wavelengths inside the green and blue spectrum by continuous-wave (CW) radiation. The here elevated helpful nonlinearity of BIBO crystal not merely boosts the effectiveness of the SHG approach but also facilitates the utilization of shorter crystal lengths—an indispensable attribute when endeavoring to engineer compact laser programs.
Even though the nonlinear coefficient of KTP crystal is huge, the laser destruction threshold is minimal, which will induce troubles such as refractive index transform and transmission loss. BIBO crystal has larger laser destruction threshold and higher next harmonic conversion performance. Though LBO and B-BBO are the most useful, They are really small in measurement and also have selected hygroscopicity, whilst BIBO crystals are non-damp and might improve to substantial dimensions. These strengths empower BIBO crystals being commonly utilised.
Abnormal optical intensities during operation may well instantaneously damage a crystal. Unfortunately, nonlinear crystals normally need to be operated not much from their optical destruction threshold to achieve a sufficiently higher conversion performance. This implies a trade-off in between conversion effectiveness and crystal lifetime.
In lots of conditions, a nonlinear crystal employed for nonlinear frequency conversion has a very long life time, which is extended than that of the whole laser process. The crystal material is basically not modified during operation. On the other hand, a reduced crystal life time can come about under a variety of instances:

Higher electrical power laser procedure: BIBO crystals are perfect for use in significant-electric power laser devices due to their higher harm threshold as well as their skill to resist higher-depth laser beams devoid of injury. This gives BIBO crystals an important gain in laser programs that require significant Vitality output.
Significant Problems Threshold: BIBO crystal provides a significant problems threshold, letting it to resist large laser electrical power with out struggling damage. This characteristic tends to make BIBO suitable for use in superior-electric power laser techniques.
