What tends to make LBO Distinctive is its mix of a large transparency range, extending in the ultraviolet for the significantly infrared, and an extremely high problems threshold.
You have to consider the wavelength and energy of the laser supply and decide on a crystal that is transparent at the supplied wavelength and might endure the laser electric power. And lastly, other aspects including the thermal balance, optical homogeneity, and nonlinear optical coefficient with the crystal also need to be deemed.
Also, it can be highly fascinating to employ a crystal substance which may be critically phase-matched at home temperature because noncritical period matching usually entails the Procedure of the crystal in the temperature-stabilized crystal oven. Nonetheless, the feasibility of crucial period matching may be presented just for adequately higher peak powers.
GWU-Lasertechnik has greater than 30 several years of encounter in distributing laser crystals. Pick GWU to gain from our huge expertise and in-discipline expertise!
5 mm to attenuate group velocity mismatch and are ideal for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The significant and noncritical period matching LBO crystals are perfect for next or 3rd harmonic generation of Nd:YAG and Yb:doped lasers.
The choice in the most suitable crystal product for any given application is commonly considerably from trivial; it must require the consideration of numerous areas. By way of example, a large nonlinearity for frequency conversion of ultrashort pulses doesn't support In the event the conversation size is strongly constrained by a considerable team velocity mismatch as well as reduced hurt threshold boundaries the relevant optical intensities.
LBO can attain the two temperature NCPM and spectral NCPM (with an extremely wide spectral bandwidth) at 1300 nm. This really is favorable for the SHG of incredibly broadband or ultrafast pulses at ~ 1300 nm.
They empower these substantial ability units to realize their peak effectiveness while making sure durability, owing to their substantial damage threshold.
Our crystals are Employed in a wide range of purposes, such as different sorts of nonlinear frequency conversion and electro-optics, but in addition quantum technological innovation.
This chapter discusses in detail the several crystal development procedures utilized for the production of LBO nonlinear crystals.
Nonetheless, if the application requires, these crystals also can endure specified elevated pressure conditions. It is always proposed to consult with a crystal pro or consult with unique producer tips to determine the exceptional circumstances to your precise LBO Crystal and software.
The Czochralski process allows for the production of large LBO crystals with outstanding crystal excellent and reduced defect density. Having said that, the method is pretty slow and needs thorough control of the temperature, rotation, and pulling amount to maintain uniform growth.
flux-developed KTP and RTP with its higher nonlinearity, also in variants with superior gray tracking resistance
Crystal expansion is often a vital stage in click here the manufacture of significant-good quality LBO nonlinear crystals. The selection of crystal development strategy can significantly influence the crystal good quality and optical Attributes from the ensuing crystal. The Czochralski, flux, and TSSG approaches will be the most commonly made use of strategies for that production of LBO nonlinear crystals, Each individual with its advantages and disadvantages.
