The acquire bandwidth e.g. of Yb:KGW and Yb:KYW is rather big in comparison with that of Yb:YAG. This permits for large wavelength tunability and for Considerably shorter pulse durations from manner-locked lasers. Values effectively underneath one hundred fs happen to be realized with passive method locking.

time. Crystals of the compound melts congruently at 1007 oC, having said that soften crystallization of top quality crystal is not possible due to section transition at ~920 oC. The highest seeded Remedy technique from

The absorption and emission spectra of Yb:KYW Crystals Exhibit powerful peaks at 980 nm and 1030 nm, respectively, ensuring effective energy conversion and large effectiveness in laser devices.

By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW a result of the very similar dimensions of these chemical aspects up to one hundred% of Yb-doping can be achieved. This distinctive characteristic permits ytterbium to go ahead and take position of yttrium with pretty much no disruption into the crystal’s lattice.

Adhesion Check Compliant with MIL-C-675C navy criteria, an adhesion exam involved making use of a tape that meets LT-ninety requirements onto the lens movie layer. The tape was affixed thoroughly and then eliminated vertically. This method was carried out three times, causing no blistering or peeling.

Spatial framework of your beam and also the corresponding intensity profiles I within the output in the laser.

For tungstates, the ytterbium doping focus can be very large with out considerable quenching since the changed ions have an exceptionally equivalent ion radius, and the inter-ion distance is pretty massive.

By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW as a result of equivalent sizes of those chemical factors nearly one hundred% of Yb-doping might be reached.

The thermal conductivity of common double tungstates is with the purchase to three–4 W/(K m) �?which isn't poor in comparison with other laser crystals (although various occasions a lot less than for YAG), and pretty substantial in contrast Along with the thermal conductivity of typical glasses.

Concurrently, a shorter laser wavelength might be obtained; it is possible to work using a quantum defect well under 1%. For a consequence, the heat era can be so smaller that this partly compensates the decreased thermal conductivity.
