This exclusive attribute of ultrafast pulses allows nonlinear optical conversation with tissue at very low In general publicity, and drives purposes which include deep-tissue multiphoton microscopy and high-precision eye surgery
The Yb:KYW crystal’s proficiency in light-weight absorption at all over 981 nm will make the crystal well matched for diode pumping. It truly is even further Improved by its impressive effectiveness in this process, coupled with its low quantum defect.
The absorption and emission spectra of Yb:KYW Crystals Exhibit sturdy peaks at 980 nm and 1030 nm, respectively, making sure economical Electrical power conversion and substantial general performance in laser programs.
This paper describes a femtosecond laser regenerative amplifier according to two Yb:KYW crystals with direct longitudinal pumping by strong linear arrays of semiconductor injection lasers owning fiber output. To avoid spectral narrowing all through amplification and the corresponding lengthening from the amplified pulse when it's compressed, a mix of two Yb:KYW crystals have been utilised, While using the spectral maxima on the amplification shifted relative to each other and with spectral profiling on the amplified radiation.
Prior to the event of Nd:YAG, Nd3+:CaWO4 was an important scarce-earth-doped laser obtain medium. It absolutely was the truth is Employed in the primary continuously functioning crystal laser.
Raman, luminescence and transmission spectra reveal optical features owing towards the presence of thulium ions, and therefore the materials could possibly be more studied from the scope of laser and luminescence programs.
Spatial framework with the beam as well as corresponding depth profiles I within the output with the laser.
For tungstates, the ytterbium doping focus can be quite higher without having considerable quenching because the changed ions have an extremely comparable ion radius, as well as inter-ion distance is relatively substantial.
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW mainly because of the identical dimensions of those chemical factors as much as 100% of Yb-doping can be realized.
Though ytterbium-doped laser obtain media frequently exhibit a little quantum defect, ytterbium-doped tungstates permit for particularly tiny values. For example, a 1030-nm Yb:YAG laser would Typically be pumped all around 940 nm, While Yb:KGW or Yb:KYW could possibly be most effectively pumped close to 981 nm.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared to its counterpart Yb:KGW, can be a outstanding product more info that performs a significant part in laser technological innovation. Its Key functionality is to produce ultrashort pulses of light, spanning just a couple hundred femtoseconds.
Talk to RP Photonics for almost any assistance relating to tungstate lasers, which include femtosecond lasers and higher-ability lasers.
