The gain bandwidth e.g. of Yb:KGW and Yb:KYW is extremely big compared with that of Yb:YAG. This permits for large wavelength tunability and for A great deal shorter pulse durations from method-locked lasers. Values properly under 100 fs have been realized with passive method locking.
This unique characteristic of ultrafast pulses allows nonlinear optical conversation with tissue at small In general exposure, and drives apps including deep-tissue multiphoton microscopy and significant-precision eye medical procedures
time. Crystals of the compound melts congruently at 1007 oC, even so melt crystallization of top quality crystal is unachievable because of phase changeover at ~920 oC. The very best seeded Resolution system from

By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW due to the comparable sizes of these chemical elements as much as a hundred% of Yb-doping may very well be attained. This distinctive attribute permits ytterbium to take the location of yttrium with pretty much no disruption to your crystal’s lattice.
Before the development of Nd:YAG, Nd3+:CaWO4 was an important scarce-earth-doped laser acquire medium. It had been in truth Employed in the initial continually functioning crystal laser.
FIG. one. Optical format of a laser read more with direct pumping Using the radiation of semiconductor injection lasers. LD is surely an IPG Photonics laser diode with fiber output
A high brightnessQ-switched oscillator and regenerative amplifier based on a twin-crystal Yb:KGW laser

Substantial-electric power repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical programs
Even though ytterbium-doped laser get media commonly show a little quantum defect, ytterbium-doped tungstates allow for specially modest values. As an example, a 1030-nm Yb:YAG laser would Generally be pumped all-around 940 nm, While Yb:KGW or Yb:KYW can be most successfully pumped about 981 nm.
Li2WO4-WO3 flux was successfully applied cutting down the growth temperature under 900 oC. In accordance with solitary crystal x-ray measurements, the crystal corresponds to your P2/n Place team.
Yb:KYW crystal (Yb-doped potassium yttrium tungstate) compared to its counterpart Yb:KGW, is a outstanding content that performs a vital purpose in laser technologies. Its Principal functionality is always to produce ultrashort pulses of sunshine, spanning just a few hundred femtoseconds.
Question RP Photonics for any assistance about tungstate lasers, which includes femtosecond lasers and large-electricity lasers.
