The comparison with Eyeglasses is appropriate Because the massive achieve bandwidth will allow e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.

We current a twin-crystal Yb:KGW laserthat iscapable to function as being a Q-switched oscillator with output electric power up to 24 W and pulse length of 20 ns,or to be a regenerative amplifier with output energy as many as 21 W and pulse period beneath 200 fs after compression of chirped pulses. Both of those lasers have excellent beam quality with beam parameter M2

By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW a result of the equivalent sizes of these chemical components nearly a hundred% of Yb-doping could be reached. This exclusive attribute permits ytterbium to go ahead and take area of yttrium with just about no disruption towards the crystal’s lattice.

Right after air drying and subsequent cleaning having a cotton cloth soaked in Liquor, the movie floor showed no indications of peeling or scratches.

PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and therefore are utilised as lasing products to deliver ultrashort (~ a hundred-two hundred fs) significant ability pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact laser systems.

Tungstates have a tendency to own significant Raman coefficients (�?Raman scattering). Hence, they are able to create considerable Raman achieve at reasonable optical intensities. It is achievable to make use of the laser crystal by itself as being a Raman converter.

For tungstates, the ytterbium doping concentration can be very superior devoid of important quenching because the changed ions have an incredibly comparable ion radius, and the inter-ion distance is pretty huge.

By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW as a result of related dimensions of these chemical aspects up to a hundred% of Yb-doping may be achieved.

The thermal conductivity of popular double tungstates is on the buy to three–4 W/(K m) �?which is not terrible when compared with other laser crystals (although several instances fewer than for YAG), and reasonably huge in comparison with the thermal click here conductivity of usual Eyeglasses.

Question RP Photonics for almost any assistance regarding tungstate lasers, together with femtosecond lasers and high-ability lasers.
