Having said that, in order to system the crystal may be very Innovative production techniques are expected. Since the dawn of this crystal, engaged on this challenge, we are actually the only real enterprise in the world which might be processed With this crystal.
When compared with BBO it attributes much larger spectral and temperature acceptance, superior angle tolerance, in addition to a scaled-down wander-off angle. from 3289 $ delivery

The standard power of the NIR laser still has the potential being improved to tens of watts which include 70 W [26] In case the double-go configuration may be utilized for your Yb:YAG SCF amplifier phase. That's why, When the conversion effectiveness of 31% from NIR to DUV could be however maintained at this larger electric power problem, the standard output electrical power of your DUV laser at 258 nm may be greater than 20 W, which might be a impressive electric power amount with the DUV laser and lead to the unanticipated DUV laser machining final results. Additionally, for prime-electricity DUV laser, the UV problems with the nonlinear crystal, such as the windows for CLBO crystal and also the mirrors, is another important parameter for long term and stable operation.
Then again, the beam high quality of this bigger electrical power DUV laser would come to be even worse on account of much more really serious thermal and nonlinear consequences. Therefore, the frequency conversion processes really should be carefully made to mitigate the aforementioned results. As a result, a significant-energy DUV laser for the FHG of 1 μm with a superb beam high-quality might be acquired and will be helpful for acquiring the shorter wavelength DUV lasers for example 193 nm by SFG.
Both equally the 1040 nm and 1078 nm laser originate from one dual-wavelength Yb-doped fiber laser. Each laser is amplified by levels of fiber amplifier and Yb-doped materials amplifier, respectively.

From the scientific and industrial purposes, the beam good quality with the DUV laser is usually an important parameter. Particularly, the beam quality on the DUV laser radically influences the laser machining benefits. The beam top quality with the DUV laser is decided by that of the basic laser as well as the crystal with the frequency conversion. Just lately, a higher-ability DUV laser (>10 W) at 258 nm was documented with a beam good quality of M2 < one.5, which was generated by FHG of a Yb:YAG laser at 1030 nm utilizing the CLBO crystal [13]. This laser would cause a far better laser machining outcome in comparison with the prior DUV lasers with more substantial M2.

Its UV absorption edge reaches 180 nm. The effective nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about 2 times as massive as that of KDP. CLBO crystals is often developed from the stoichiometric melt with reduced viscosity.
