This exceptional attribute of ultrafast pulses permits nonlinear optical conversation with tissue at minimal All round exposure, and drives applications which include deep-tissue multiphoton microscopy and higher-precision eye surgical treatment

We existing a dual-crystal Yb:KGW laserthat iscapable to function as a Q-switched oscillator with output energy approximately 24 W and pulse duration of twenty ns,or being a regenerative amplifier with output power up to 21 W and pulse duration beneath 200 fs soon after compression of chirped pulses. Both of those lasers have superb beam good quality with beam parameter M2

This paper describes a femtosecond laser regenerative amplifier determined by two Yb:KYW crystals with direct longitudinal pumping by potent linear arrays of semiconductor injection lasers owning fiber output. To circumvent spectral narrowing throughout amplification along with the corresponding lengthening in the amplified pulse when it is compressed, a combination of two Yb:KYW crystals ended up applied, With all the spectral maxima of the amplification shifted relative to one another and with spectral profiling in the amplified radiation.

In advance of the development of Nd:YAG, Nd3+:CaWO4 was a vital unusual-earth-doped laser gain medium. It had been actually used in the first continuously running crystal laser.

A substantial brightnessQ-switched oscillator and regenerative amplifier dependant on a twin-crystal Yb:KGW laser

... at fifty percent-top had been generated inside a grasp oscillator with selfsynchronization with the axial modes, explained within our before write-up. 21 The new edition from the laser, as opposed to that described in our previously write-up, employed an Yb:KYW crystal with the N pcut (optical axis N p from the index ellipsoid was parallel towards the propagation way with the laser radiation), While using the polarization in the created radiation directed alongside the N m axis.

... Don't just the situation of crystal while in the cavity but also the amplification axis of crystal impacts the laser operation drastically, since the absorption and emission cross sections of the crystal are pretty diverse in accordance with the orientation on the crystal.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) as compared to its counterpart Yb:KGW, is actually a outstanding materials that performs a very important job in laser technological know-how. Its read more Most important purpose is usually to create ultrashort pulses of light, spanning just some hundred femtoseconds.
