The get bandwidth e.g. of Yb:KGW and Yb:KYW is extremely massive as opposed with that of Yb:YAG. This allows for wide wavelength tunability and for Considerably shorter pulse durations from manner-locked lasers. Values perfectly underneath a hundred fs have been accomplished with passive mode locking.

We present a twin-crystal Yb:KGW laserthat iscapable to operate like a Q-switched oscillator with output electric power as many as 24 W and pulse size of twenty ns,or like a regenerative amplifier with output electrical power nearly 21 W and pulse period below two hundred fs soon after compression of chirped pulses. Equally lasers have superb beam high quality with beam parameter M2
Color-coded reflectivity of a Bragg mirror like a purpose of wavelength and angle of your incident beam.
Optical structure of a laser with immediate pumping Together with the radiation of semiconductor injection lasers. LD is surely an IPG Photonics laser diode with fiber output of the radiation, WP is often a 50 percent-wave plate, CL is often a collimating lens, FL is often a concentrating lens, AE is surely an Lively component constructed from an Yb:KYW crystal, DM is really a spherical dichroic mirror, M1-M6 tend to be the cavity mirrors, OC will be the output mirror, and SAM can be a semiconductor saturable-absorber mirror.
The monoclinic crystal structures brings about a purely natural birefringence, assisting to prevent thermally induced polarization rotation and depolarization loss.

Spatial framework on the beam along with the corresponding intensity profiles I at the output of your laser.
For tungstates, the ytterbium doping focus can be extremely substantial with out important quenching as the replaced ions have an exceptionally comparable ion radius, as well as inter-ion distance is pretty huge.
By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW a result of the equivalent sizes of such chemical aspects as much as a hundred% of Yb-doping may very well be attained.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared with its counterpart Yb:KGW, is often a amazing substance that plays a crucial function in laser technologies. Its primary purpose is usually to create ultrashort pulses of sunshine, spanning just more info a couple hundred femtoseconds.
