The attain bandwidth e.g. of Yb:KGW and Yb:KYW is very large compared with that of Yb:YAG. This allows for broad wavelength tunability and for A lot shorter pulse durations from mode-locked lasers. Values well below a hundred fs are actually attained with passive method locking.
The comparison with Eyeglasses is suitable For the reason that big gain bandwidth makes it possible for e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
The Yb:KYW crystal’s proficiency in light absorption at all-around 981 nm will make the crystal well matched for diode pumping. It's further more Increased by its extraordinary efficiency in this process, coupled with its low quantum defect.

Optical format of the laser with immediate pumping Together with the radiation of semiconductor injection lasers. LD is definitely an IPG Photonics laser diode with fiber output of the radiation, WP is actually a fifty percent-wave plate, CL can be a collimating lens, FL is usually a concentrating lens, AE is really an Energetic component made from an Yb:KYW crystal, DM is a spherical dichroic mirror, M1-M6 are definitely the cavity mirrors, OC will be the output mirror, and SAM is really a semiconductor saturable-absorber mirror.
After air drying and subsequent cleaning which has a cotton cloth soaked in Alcoholic beverages, the film surface showed no signs of peeling or scratches.
FIG. one. Optical format of a laser with immediate pumping With all the radiation of semiconductor injection lasers. LD is definitely an IPG Photonics laser diode with fiber output
Spatial structure on the beam along with the corresponding intensity profiles I with the output in the laser.
