The get bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly significant in contrast with that of Yb:YAG. This enables for extensive wavelength tunability and for much shorter pulse durations from mode-locked lasers. Values effectively underneath one hundred fs are obtained with passive manner locking.
This special attribute of ultrafast pulses permits nonlinear optical interaction with tissue at lower All round publicity, and drives purposes like deep-tissue multiphoton microscopy and substantial-precision eye surgery
We present a twin-crystal Yb:KGW laserthat iscapable to function like a Q-switched oscillator with output electric power approximately 24 W and pulse length of twenty ns,or as being a regenerative amplifier with output power up to 21 W and pulse length below two hundred fs following compression of chirped pulses. Both of those lasers have exceptional beam high quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Display screen robust peaks at 980 nm and 1030 nm, respectively, making certain successful Electricity conversion and superior overall performance in laser methods.
By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW due to the equivalent measurements of those chemical things nearly a hundred% of Yb-doping could be obtained. This distinctive characteristic permits ytterbium to take the check here place of yttrium with virtually no disruption to the crystal’s lattice.
Right before the development of Nd:YAG, Nd3+:CaWO4 was an important rare-earth-doped laser obtain medium. It had been in reality Employed in the first continually running crystal laser.

Concurrently, a shorter laser wavelength is often acquired; it is achievable to function with a quantum defect perfectly underneath 1%. For a consequence, the heat technology could be so small that this partly compensates the lower thermal conductivity.
