The get bandwidth e.g. of Yb:KGW and Yb:KYW is very huge as opposed with that of Yb:YAG. This enables for extensive wavelength tunability and for Considerably shorter pulse durations from mode-locked lasers. Values nicely down below one hundred fs are already achieved with passive mode locking.
The comparison with Eyeglasses is appropriate Because the big gain bandwidth will allow e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
We present a twin-crystal Yb:KGW laserthat iscapable to work being a Q-switched oscillator with output electric power nearly 24 W and pulse duration of twenty ns,or as a regenerative amplifier with output energy as much as 21 W and pulse length under two hundred fs following compression of chirped pulses. Each lasers have great beam excellent with beam parameter M2

Ultrafast lasers, with pulse widths of some picoseconds (10−twelve s) or significantly less, permit time resolution needed in laser-thrilled fluorescence life span spectroscopy and imaging approaches.Also, they produce superior pulse peak powers at significant repetition costs and reasonable average output powers.
The monoclinic crystal buildings results in a natural birefringence, assisting to stay clear of thermally induced polarization rotation and depolarization decline.

A high brightnessQ-switched oscillator and regenerative amplifier based on a twin-crystal Yb:KGW laser
For tungstates, the ytterbium doping concentration can be extremely higher without the need of substantial quenching because the replaced ions have an exceptionally equivalent ion radius, as well as inter-ion length is fairly substantial.
Having said that, once Nd3+:YAG became commercially obtainable, the fascination in CaWO4 dropped sharply. In later on decades, certain other tungstate crystals started to entice plenty of awareness.
Even though ytterbium-doped laser achieve media normally exhibit a small quantum defect, ytterbium-doped tungstates permit for particularly compact values. One example is, a 1030-nm Yb:YAG laser would Ordinarily be pumped all-around 940 nm, While Yb:KGW or Yb:KYW might be most competently pumped all over 981 nm.
