In simple phrases, the Yb:KYW crystal has located its market in large-electric power laser apps resulting from its capacity to make substantial Vitality ultrashort laser pulses though protecting a compact sizing. The interaction of its features �?seamless ytterbium substitution, strong absorption properties, ultrashort pulse era and effectiveness in Vitality conversion �?positions the Yb:KYW crystal as being a cornerstone in the laser technology, masking diverse fields ranging from scientific investigate to industrial programs.
The comparison with glasses is appropriate since the large gain bandwidth allows e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
The Yb:KYW crystal’s proficiency in light absorption at all around 981 nm will make the crystal well suited for diode pumping. It can be more enhanced by its outstanding performance in this process, coupled with its very low quantum defect.
The absorption and emission spectra of Yb:KYW Crystals Screen solid peaks at 980 nm and 1030 nm, respectively, making sure efficient Vitality conversion and higher effectiveness in laser units.
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW because of the comparable measurements of those chemical things up to a hundred% of Yb-doping could possibly be realized. This one of a kind characteristic permits ytterbium to go ahead and take area of yttrium with almost no disruption on the crystal’s lattice.
Right after air drying and subsequent cleansing by using a cotton fabric soaked in alcohol, the film surface showed no indications of peeling or scratches.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and are used as lasing materials to deliver ultrashort (~ a hundred-200 fs) large energy pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes functioning at 981 nm supports compact laser devices.
5 mm aside from the center of the beam caustic. To be able to Verify the manner matching simulation, we done the experiment with Ng-Lower crystal oscillator, which was created Beforehand and in a same issue with simulation [eleven]. As demonstrated in Determine 3(b) with pink dots and line, the CW output electricity is highly depending on the place of laser crystal as well as experimental end result coincides well with simulation end result. To be a Be aware, multimode Procedure happened in experiment when the measurement of your pump beam is bigger than TEM00 cavity method and it brings about bigger CW output power inside the displacement area underneath 3.5 mm.

By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW mainly because of the very similar dimensions of those chemical components nearly one hundred% of Yb-doping might be realized.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison to its counterpart Yb:KGW, is actually a exceptional content that plays an important role in laser technology. Its Main functionality is usually to create ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
Request RP Photonics for virtually any information regarding tungstate lasers, including femtosecond lasers and significant-power lasers.
