In realistic phrases, the Yb:KYW crystal has discovered its niche in high-power laser purposes as a consequence of its capacity to make large Power ultrashort laser pulses while retaining a compact sizing. The interplay of its functions �?seamless ytterbium substitution, powerful absorption characteristics, ultrashort pulse technology and effectiveness in energy conversion �?positions the Yb:KYW crystal to be a cornerstone while in the laser technological innovation, covering assorted fields ranging from scientific investigate to industrial programs.
The comparison with glasses is acceptable Considering that the big achieve bandwidth will allow e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
time. Crystals of the compound melts congruently at 1007 oC, on the other hand melt crystallization of top of the range crystal is difficult as a result of phase transition at ~920 oC. The highest seeded Answer method from
Color-coded reflectivity of a Bragg mirror for a function of wavelength and angle in the incident beam.
Optical structure of a laser with direct pumping with the radiation of semiconductor injection lasers. LD is definitely an IPG Photonics laser diode with fiber output from the radiation, WP is actually a fifty percent-wave plate, CL is actually a collimating lens, FL is a focusing lens, AE is definitely an Energetic component comprised of an Yb:KYW crystal, DM is usually a spherical dichroic mirror, M1-M6 will be the cavity mirrors, OC is definitely the output mirror, and SAM is really a semiconductor saturable-absorber mirror.
Adhesion Examination Compliant with MIL-C-675C military requirements, an adhesion test included applying a tape that meets LT-90 specifications onto the lens film layer. The tape was affixed completely after which taken out vertically. This method was performed three times, causing no blistering or peeling.
Raman, luminescence and transmission spectra expose optical capabilities owing towards the existence of thulium ions, and for that reason the supplies could be even further examined inside the scope of laser and luminescence applications.
Tungstates are likely to have large Raman coefficients (�?Raman scattering). For that reason, they might generate considerable Raman obtain at reasonable optical intensities. It is achievable to utilize the laser crystal alone for a Raman converter.
For tungstates, the ytterbium doping focus can be quite higher without having important quenching since the replaced ions have an exceedingly very similar ion radius, along with the inter-ion distance is pretty massive.
... Don't just the posture of crystal during the cavity but also the amplification axis of crystal affects the laser Procedure enormously, as the absorption and emission cross sections of your crystal are pretty distinctive in accordance with the orientation on the crystal.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison with its counterpart Yb:KGW, is actually a impressive product that performs a very important purpose in laser technological know-how. Its Key purpose is always to produce ultrashort pulses of sunshine, spanning just some hundred femtoseconds.
Request RP Photonics for any assistance regarding tungstate lasers, together with femtosecond lasers and substantial-energy lasers.
