In sensible phrases, the Yb:KYW crystal has observed its specialized niche in superior-power laser applications due to its capacity to make higher Power ultrashort laser pulses though retaining a compact dimension. The interaction of its characteristics �?seamless ytterbium substitution, solid absorption traits, ultrashort pulse technology and efficiency in energy conversion �?positions the Yb:KYW crystal to be a cornerstone in the laser technology, masking diverse fields ranging from scientific analysis to industrial programs.

The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison with its counterpart Yb:KGW, can be a outstanding product that plays a vital job in laser engineering. Its Key functionality is to produce ultrashort pulses of light, spanning just a few hundred femtoseconds.

We present a dual-crystal Yb:KGW laserthat iscapable to function to be a Q-switched oscillator with output electrical power as many as 24 W and pulse duration of twenty ns,or to be a regenerative amplifier with output energy around 21 W and pulse length under 200 fs immediately after compression of chirped pulses. Both equally lasers have fantastic beam quality with beam parameter M2

Coloration-coded reflectivity of a Bragg mirror like a functionality of wavelength and angle from the incident beam.

By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW due to the related sizes of those chemical features around a hundred% of Yb-doping might be realized. This distinctive characteristic permits ytterbium to go ahead and take position of yttrium with nearly no disruption towards the crystal’s lattice.

The monoclinic crystal structures leads to a organic birefringence, helping to more info steer clear of thermally induced polarization rotation and depolarization decline.

By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW as a result of equivalent sizes of such chemical things as many as one hundred% of Yb-doping might be reached.

The thermal conductivity of frequent double tungstates is of your order to 3–4 W/(K m) �?which is not negative in comparison with other laser crystals (Though a number of situations lower than for YAG), and fairly big in contrast Using the thermal conductivity of common glasses.

Concurrently, a shorter laser wavelength might be acquired; it can be done to function with a quantum defect perfectly under 1%. For a consequence, the heat era can be so smaller this partly compensates the decrease thermal conductivity.
