In realistic phrases, the Yb:KYW crystal has observed its area of interest in significant-electric power laser applications because of its capability to produce high energy ultrashort laser pulses though protecting a compact dimensions. The interplay of its features �?seamless ytterbium substitution, sturdy absorption qualities, ultrashort pulse technology and efficiency in Electricity conversion �?positions the Yb:KYW crystal like a cornerstone in the laser technological know-how, covering numerous fields ranging from scientific investigate to industrial programs.
The comparison with glasses is appropriate since the significant get bandwidth makes it possible for e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
The Yb:KYW crystal’s proficiency in mild absorption at all around 981 nm makes the crystal well suited for diode pumping. It truly is even further Increased by its remarkable performance in this method, coupled with its low quantum defect.

This paper describes a femtosecond laser regenerative amplifier based upon two Yb:KYW crystals with immediate longitudinal pumping by strong linear arrays of semiconductor injection lasers obtaining fiber output. To avoid spectral narrowing in the course of amplification as well as the corresponding lengthening of the amplified pulse when it is compressed, a mix of two Yb:KYW crystals were being applied, Together with the spectral maxima from the amplification shifted relative to one another and with spectral profiling from the amplified radiation.
After air drying and subsequent cleansing using a cotton cloth soaked in Liquor, the film surface area confirmed no indications of peeling or scratches.

Spatial construction in the beam as well as the corresponding intensity profiles I at the output on the laser.
For tungstates, the ytterbium doping focus can be very large without considerable quenching as the changed ions have an extremely comparable ion radius, as well as inter-ion distance is comparatively substantial.
High-ability repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical apps
