We existing a twin-crystal Yb:KGW laserthat iscapable to work as being a Q-switched oscillator with output electrical power as much as 24 W and pulse size of twenty ns,or like a regenerative amplifier with output power up to 21 W and pulse period down below two hundred fs after compression of chirped pulses. The two lasers have excellent beam excellent with beam parameter M2

Optical format of the laser with direct pumping With all the radiation of semiconductor injection lasers. LD is surely an IPG Photonics laser diode with fiber output on the radiation, WP is a fifty percent-wave plate, CL can be a collimating lens, FL is often a concentrating lens, AE is definitely an active aspect produced from an Yb:KYW crystal, DM is actually a spherical dichroic mirror, M1-M6 will be the cavity mirrors, OC is definitely the output mirror, and SAM is actually a semiconductor saturable-absorber mirror.
The monoclinic click here crystal buildings brings about a purely natural birefringence, helping to stay away from thermally induced polarization rotation and depolarization reduction.
Raman, luminescence and transmission spectra reveal optical options owing for the presence of thulium ions, and so the elements could be additional analyzed inside the scope of laser and luminescence purposes.
Spatial framework of your beam plus the corresponding intensity profiles I on the output from the laser.
For tungstates, the ytterbium doping concentration can be very large without important quenching because the replaced ions have an exceedingly very similar ion radius, along with the inter-ion distance is relatively big.
Large-electrical power repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical programs
The thermal conductivity of typical double tungstates is of your purchase to three–four W/(K m) �?which is not lousy in comparison with other laser crystals (Even though quite a few instances less than for YAG), and reasonably large in comparison with the thermal conductivity of standard Eyeglasses.
This tandem of characteristics has far-achieving implications, especially in the construction of compact nevertheless powerfull lasers.
