The get bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly substantial when compared with that of Yb:YAG. This enables for huge wavelength tunability and for much shorter pulse durations from method-locked lasers. Values properly below one hundred fs are obtained with passive method locking.
Besides its use like a Raman crystal, KGW is likewise Utilized in other optical purposes, for example in laser methods and for a scintillator in health care imaging.
The monoclinic crystal structures leads to a organic birefringence, assisting to prevent thermally induced polarization rotation and depolarization reduction.

Comparison of spectral Power densities of supercontinua produced while in the problems of optimal pumping during the investigated products.
Ask RP Photonics for any tips regarding tungstate lasers, such as femtosecond lasers and significant-ability lasers.
The red-shifted Element of the SC spectrum in BGO has the bottom spectral Strength density, which can be 1–two orders of magnitude decreased than in the remainder of the elements. Nonetheless, extremely low Electrical power threshold of SC era, in addition to small best pump Vitality in BGO, ought to be identified. The approximated spectral energy densities generated in LSO and LYSO are really similar to YAG all over the significant Element of the SC spectrum. One of the most fascinating acquiring in that regard is GGG crystal, which, In spite of incredibly moderate blue-shifted spectral broadening, makes the largest spectral purple-change and the highest spectral Strength density in the 1600�?000 nm selection, which is almost an purchase of magnitude better than that created in YAG.
Whilst BGO, GGG, YSO, LSO and LYSO at times serve as laser hosts37, These are mostly discovered as productive scintillators, whose scintillation Houses are analyzed rather well38. On the other hand, the nonlinear optical Attributes of those crystals and so their prospective to serve as nonlinear elements for SC generation in particular, and some more info other experiments regarding nonlinear propagation of rigorous femtosecond laser pulses, remain extremely poorly researched. To date, GGG, LT23,twenty five and YSO24 were only sketchily examined for SC technology with Ti:sapphire laser pumping, on the other hand, to the most effective of our information, none of the investigated components had been examined with Yb-laser pumping, specifically for what issues their effectiveness at really substantial (tens to many kHz) pulse repetition premiums.
Tungstates are likely to possess significant Raman coefficients (�?Raman scattering). Consequently, they will generate considerable Raman attain at moderate optical intensities. It is feasible to make use of the laser crystal alone to be a Raman converter.
