They will also be useful for frequency doubling invisible just one-micron mild into 532nm noticeable inexperienced gentle, an application which includes Earlier belonged to KTP crystals.
Even when the crystal product or coating will not be sensitive to h2o, modest h2o droplets may emphasis laser radiation much more tightly than underneath typical Procedure, and therefore harm the crystal content.
Also, it could be remarkably fascinating to employ a crystal material which can be critically section-matched at place temperature mainly because noncritical section matching normally consists of the operation from the crystal inside a temperature-stabilized crystal oven. However, the feasibility of important stage matching could be specified just for adequately superior peak powers.
Raman spectroscopy may be used to establish impurities and defects in LBO nonlinear crystals that can affect their functionality in many applications. Raman spectroscopy can also be made use of to determine the crystal quality and section purity.
Dennis is undoubtedly an engineer with about 45 decades of encounter in fabrication, testing, and material analysis for top precision optics, with in depth arms-on working experience. Additional on the creator are available listed here.
The most typical utilization of LBO is in short pulse, substantial pulse charge lasers; the upper energy density the better. Additionally it is pretty like minded for non-essential section matching (NCPM) for frequency conversion of CW and quasi-CW radiation, at ninety% conversion efficiency devoid of walk-off.
Crystals for NCPM at an elavated temperature can be premounted within an oven with precision controller. Crystals employed check here at ~ 20 - 50 oC can even be premounted inside of a compatible water-cooled or TEC (ThermoElectric Cooler) cooled mount on ask for.
You should use "Incorporate to Cart" to place the intriguing items within the browsing cart. Look into with on-line payment or inquire us for the prices/availability via the procuring cart.
If the crystal surfaces remain “soiled�?just after the above mentioned cleansing processes, the surfaces might need been broken. Please Call us for rework of your crystals.
In general, the characterization solutions reviewed During this chapter deliver precious insights into your approaches utilized for the characterization of LBO nonlinear crystals.

One of the most widespread purposes is frequency doubling, in which LBO Crystals successfully transform the frequency of the substantial electric power laser, effectively halving the wavelength and opening up a spectrum of choices for laser programs.
) to blow off dust as well as other free contaminants first. If a dry nitrogen line is accessible during the lab, an air gun can be made use of to blow away dust particles. Blow off the area Carefully. Usually do not blow off the crystal alone from a hand!
The BO3 groups are organized in a triangular configuration, forming a six-membered ring during the crystal construction. The Li ions occupy the interstitial web-sites between the BO3 groups.
