The attain bandwidth e.g. of Yb:KGW and Yb:KYW is quite huge compared with that of Yb:YAG. This permits for huge wavelength tunability and for Considerably shorter pulse durations from manner-locked lasers. Values very well below 100 fs have been accomplished with passive method locking.
This one of a kind attribute of ultrafast pulses permits nonlinear optical conversation with tissue at very low General exposure, and drives applications like deep-tissue multiphoton microscopy and significant-precision eye surgical procedures
The Yb:KYW crystal’s proficiency in light-weight absorption at close to 981 nm makes the crystal well suited for diode pumping. It is further Improved by its extraordinary performance in this process, coupled with its low quantum defect.
The absorption and emission spectra of Yb:KYW Crystals Show solid peaks at 980 nm and 1030 nm, respectively, making sure efficient Power conversion and higher functionality in laser programs.
Optical format of the laser with direct pumping Using the radiation of semiconductor injection lasers. LD is definitely an IPG Photonics laser diode with fiber output of your radiation, WP can be a fifty percent-wave plate, CL is usually a collimating lens, FL is a concentrating lens, AE can be an active element comprised of an Yb:KYW crystal, DM can be a spherical dichroic mirror, M1-M6 are the cavity mirrors, OC will be the output mirror, and SAM is usually a semiconductor saturable-absorber mirror.
Just before the event of Nd:YAG, Nd3+:CaWO4 was a vital uncommon-earth-doped laser obtain medium. It absolutely was in reality Utilized in the main constantly running crystal laser.

Spatial structure of the beam as well as corresponding depth profiles I with the output on the laser.
For tungstates, the ytterbium doping focus can be very superior devoid of substantial quenching as the changed ions have an incredibly similar ion radius, as well as the inter-ion distance is fairly substantial.
Nevertheless, after Nd3+:YAG became commercially readily available, the interest in CaWO4 dropped sharply. In later a long time, selected other tungstate crystals began to attract lots of more info focus.
