The get bandwidth e.g. of Yb:KGW and Yb:KYW is extremely massive as opposed with that of Yb:YAG. This allows for vast wavelength tunability and for Considerably shorter pulse durations from manner-locked lasers. Values properly below 100 fs are realized with passive method locking.
It is a preview of membership material, log in by way of an establishment to examine access. Access this short article
We current a dual-crystal Yb:KGW laserthat iscapable to work for a Q-switched oscillator with output electricity around 24 W and pulse size of 20 ns,or like a regenerative amplifier with output electrical power around 21 W and pulse duration below two hundred fs after compression of chirped pulses. Both lasers have superb beam high quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Show sturdy peaks at 980 nm and 1030 nm, respectively, guaranteeing productive Strength conversion and significant general performance in laser systems.
Optical structure of a laser with immediate pumping Together with the radiation of semiconductor injection lasers. LD is undoubtedly an IPG Photonics laser diode with fiber output from the radiation, WP is usually a fifty percent-wave plate, CL is usually a collimating lens, FL is usually a focusing lens, AE can be an active aspect produced from an Yb:KYW crystal, DM is often a spherical dichroic mirror, M1-M6 will be the cavity mirrors, OC is definitely the output mirror, and SAM is really a semiconductor saturable-absorber mirror.
The monoclinic crystal constructions ends in a pure birefringence, helping to keep away from thermally induced polarization rotation and depolarization loss.
Raman, luminescence and transmission spectra expose optical options owing to the presence of thulium ions, and thus the components may be even further examined from the scope of laser and luminescence apps.
Spatial framework from the beam and the corresponding depth profiles I in the click here output of your laser.

Higher-electric power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical programs
Though ytterbium-doped laser gain media usually exhibit a small quantum defect, ytterbium-doped tungstates permit for specifically tiny values. By way of example, a 1030-nm Yb:YAG laser would Commonly be pumped all around 940 nm, While Yb:KGW or Yb:KYW may very well be most successfully pumped all around 981 nm.
