The gain bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly significant as opposed with that of Yb:YAG. This allows for extensive wavelength tunability and for A great deal shorter pulse durations from manner-locked lasers. Values effectively underneath a hundred fs have already been realized with passive manner locking.
This special attribute of ultrafast pulses allows nonlinear optical interaction with tissue at very low Total publicity, and drives programs such as deep-tissue multiphoton microscopy and superior-precision eye medical procedures
Femtosecond laser based on Yb:KYW crystals with suppression of spectral narrowing inside a regenerative amplifier by spectral profiling of the heart beat
In case you are aiming to obtain This website working with an nameless Personal/Proxy community, remember to disable that and take a look at accessing website yet again.
This paper describes a femtosecond laser regenerative amplifier according to two Yb:KYW crystals with direct longitudinal pumping by potent linear arrays of semiconductor injection lasers getting fiber output. To stop spectral narrowing in the course of amplification as well as the corresponding lengthening from the amplified pulse when it's compressed, a mix of two Yb:KYW crystals had been used, with the spectral maxima from the amplification shifted relative to one another and with spectral profiling in the amplified radiation.
Adhesion Examination Compliant with MIL-C-675C military services requirements, an adhesion examination included making use of a tape that fulfills LT-ninety requirements on to the lens film layer. The tape was affixed completely after which you can removed vertically. This method was done thrice, causing no blistering or peeling.
Raman, luminescence and transmission spectra expose optical features owing into the presence of thulium ions, check here and so the resources may be further more studied from the scope of laser and luminescence purposes.

By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW due to the similar sizes of such chemical aspects nearly 100% of Yb-doping may very well be accomplished.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) compared to its counterpart Yb:KGW, is often a extraordinary product that performs a vital position in laser technological innovation. Its Principal operate would be to create ultrashort pulses of light, spanning just a few hundred femtoseconds.
