The comparison with glasses is suitable For the reason that huge achieve bandwidth will allow e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
We existing a twin-crystal Yb:KGW laserthat iscapable to work being a Q-switched oscillator with output energy approximately 24 W and pulse duration of twenty ns,or for a regenerative amplifier with output energy as many as 21 W and pulse length below 200 fs right after compression of chirped pulses. Both of those lasers have outstanding beam high-quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Exhibit strong peaks at 980 nm and 1030 nm, respectively, ensuring productive Electricity conversion and superior general performance in laser units.
This paper describes a femtosecond laser regenerative amplifier dependant on two Yb:KYW crystals with direct longitudinal pumping by potent linear arrays of semiconductor injection lasers possessing fiber output. To circumvent spectral narrowing during amplification along with the corresponding lengthening on the amplified pulse when it can be compressed, a mix of two Yb:KYW crystals have been utilised, Along with the spectral maxima of your amplification shifted relative to one another and with spectral profiling on the amplified radiation.
The monoclinic crystal constructions leads to a natural birefringence, helping to steer clear of thermally induced polarization rotation and depolarization loss.
Raman, luminescence and transmission spectra expose optical capabilities owing on the presence of thulium ions, and thus the elements may be further more examined within the scope of laser and luminescence programs.
A large brightnessQ-switched oscillator and regenerative amplifier according to a twin-crystal Yb:KGW laser
... at 50 %-peak ended up produced in a very learn oscillator with selfsynchronization of the more info axial modes, explained in our earlier article. 21 The new edition of your laser, in contrast to that described within our before posting, made use of an Yb:KYW crystal using an N pcut (optical axis N p in the index ellipsoid was parallel to the propagation course of the laser radiation), Using the polarization with the created radiation directed together the N m axis.
... Not simply the placement of crystal in the cavity and also the amplification axis of crystal impacts the laser Procedure tremendously, because the absorption and emission cross sections of your crystal are very various based on the orientation from the crystal.

This tandem of characteristics has far-reaching implications, notably in the construction of compact but powerfull lasers.

At the same time, a shorter laser wavelength is usually received; it is possible to work by using a quantum defect well down below one%. Being a consequence, the heat era can be so smaller that this partly compensates the decreased thermal conductivity.
