This distinctive 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 surgery
We current a dual-crystal Yb:KGW laserthat iscapable to function being a Q-switched oscillator with output ability approximately 24 W and pulse duration of 20 ns,or for a regenerative amplifier with output electricity nearly 21 W and pulse period under 200 fs just after compression of chirped pulses. Each lasers have fantastic beam top quality with beam parameter M2

This paper describes a femtosecond laser regenerative amplifier depending on two Yb:KYW crystals with direct longitudinal pumping by potent linear arrays of semiconductor injection lasers having fiber output. To circumvent spectral narrowing all through amplification plus the corresponding lengthening of the read more amplified pulse when it really is compressed, a combination of two Yb:KYW crystals were being utilised, With all the spectral maxima of the amplification shifted relative to each other and with spectral profiling of the amplified radiation.
Prior to the event of Nd:YAG, Nd3+:CaWO4 was an important unusual-earth-doped laser attain medium. It was the truth is Employed in the very first continually functioning crystal laser.
Raman, luminescence and transmission spectra expose optical options owing to the presence of thulium ions, and thus the elements can be even more studied inside the scope of laser and luminescence purposes.
Spatial construction with the beam as well as corresponding intensity profiles I on the output on the laser.

Superior-electrical power repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical purposes
Even though ytterbium-doped laser get media frequently show a little quantum defect, ytterbium-doped tungstates allow for especially little values. As an example, a 1030-nm Yb:YAG laser would Typically be pumped around 940 nm, Whilst Yb:KGW or Yb:KYW can be most successfully pumped all over 981 nm.
This tandem of attributes has significantly-achieving implications, significantly in the construction of compact nevertheless powerfull lasers.
