The achieve bandwidth e.g. of Yb:KGW and Yb:KYW is very large in comparison with that of Yb:YAG. This permits for vast wavelength tunability and for A lot shorter pulse durations from method-locked lasers. Values perfectly below a hundred fs happen to be reached with passive method locking.

This exceptional characteristic of ultrafast pulses permits nonlinear optical interaction with tissue at very low overall exposure, and drives programs including deep-tissue multiphoton microscopy and large-precision eye surgical treatment

time. Crystals on the compound melts congruently at 1007 oC, even so melt crystallization of high quality crystal is unachievable on account of period transition at ~920 oC. The very best seeded Option approach from

By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW due to equivalent measurements of those chemical aspects approximately one hundred% of Yb-doping may very well be attained. This exclusive characteristic permits ytterbium to take the location of yttrium with practically no disruption towards the crystal’s lattice.

Adhesion Check Compliant with MIL-C-675C army criteria, an adhesion exam involved implementing a tape that satisfies LT-ninety technical specs on to the lens movie layer. The tape was affixed fully then taken website off vertically. This technique was done thrice, causing no blistering or peeling.

By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW as a result of comparable dimensions of those chemical elements as many as 100% of Yb-doping can be realized.

Simultaneously, a shorter laser wavelength could be obtained; it is achievable to operate with a quantum defect perfectly under 1%. Being a consequence, the heat era can be so smaller that this partly compensates the decreased thermal conductivity.
