In comparison with BBO it options greater spectral and temperature acceptance, better angle tolerance, plus a more compact stroll-off angle. from 3289 $ shipping and delivery

The key difficulty of ultraviolet coherent gentle supply largely concentrates on the event of nonlinear optical frequency conversion crystal in ultraviolet band. The nonlinear optical crystal is without doubt one of the conditions for frequency transformation, so the growth, dimension, hurt resistance, conversion efficiency and allowable parameter variety of nonlinear optical crystal are expected Increasingly more.

Due to thermal lens influence while in the reliable-state lasers, if the heating administration is insufficient, It isn't quick to get the stable-point out laser by using a high electric power as well as a superior beam top quality concurrently. Lately, with the development of The skinny disk laser and one-crystal fiber (SCF) laser, a high-electrical power laser at the elemental wavelength (one μm) were realized with a fantastic beam high quality In spite of a TEM00 manner beam [four,24], which would be excellent candidates for the basic of your DUV laser generation. A further candidate for the basic will be the superior-electrical power fiber laser which may very well be realized by coherent beam blend with M2 worth under 1.

During the scientific and industrial purposes, the beam excellent with the DUV laser can be a vital parameter. Notably, the beam high quality of the DUV laser considerably has an effect on the laser machining benefits. The beam top quality with the DUV laser is determined by that of the basic laser as well as crystal for your frequency conversion. A short while ago, a higher-ability DUV laser (>10 W) at 258 nm was documented that has a beam quality of M2 < 1.5, which was generated by FHG of a Yb:YAG laser at 1030 nm using the CLBO crystal [13]. This laser read more would cause a better laser machining outcome when compared with the past DUV lasers with larger sized M2.
The heartbeat period of the second Stokes gentle was shortened to five ns as proven in Figure 7a, one-shot photo from the oscilloscope, that's a standard phenomenon in Raman laser [44] whilst the heart beat length with the pump laser was ten ns.
Cesium Lithium Borate (CsLiB6O10 or CLBO) is the best non-linear crystal which generates ultraviolet harmonics in the Nd:YAG fundamental laser wavelength. To be able to enhance the destruction threshold, lower CLBO surface roughness, by extremely-precision machining, is needed. Since the CLBO crystal has simple hydroscopic reaction and micro scratches in machining, ultra-specific machining from the CLBO crystal is usually a hard technical dilemma.
Tunable ultraviolet laser source according to sound-state dye laser engineering and CsLiB6O10 harmonic generation
Its UV absorption edge reaches 180 nm. The efficient nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about 2 times as huge as that of KDP. CLBO crystals could be developed with the stoichiometric melt with lessen viscosity.
