The obtain bandwidth e.g. of Yb:KGW and Yb:KYW may be very huge as opposed with that of Yb:YAG. This permits for broad wavelength tunability and for Considerably shorter pulse durations from method-locked lasers. Values perfectly below 100 fs have already been reached with passive method locking.
That is a preview of subscription information, log in by way of an institution to examine accessibility. Obtain this post
time. Crystals of the compound melts congruently at 1007 oC, having said that soften crystallization of top quality crystal is extremely hard resulting from stage changeover at ~920 oC. The highest seeded solution system from
The absorption and emission spectra of Yb:KYW Crystals Display screen strong peaks at 980 nm and 1030 nm, respectively, making certain productive Electricity conversion and superior overall performance in laser methods.
Optical format of the laser with direct pumping with the radiation of semiconductor injection lasers. LD can be an IPG Photonics laser diode with fiber output on the radiation, WP is a 50 percent-wave plate, CL is often a collimating lens, FL is usually a concentrating lens, AE is surely an Lively aspect produced from an Yb:KYW crystal, DM is usually 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.
Adhesion Examination Compliant with MIL-C-675C military services benchmarks, an adhesion test involved applying a tape that meets LT-90 specs onto the lens film layer. The tape was affixed thoroughly and afterwards taken off vertically. This course of action was executed thrice, leading to no blistering or peeling.

Spatial composition with the beam plus the corresponding depth profiles I within the output with the laser.
For tungstates, the ytterbium doping focus can be very substantial without important quenching as the replaced ions have an exceptionally comparable ion radius, along with the inter-ion distance is fairly significant.
Superior-power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical apps
Whilst ytterbium-doped laser obtain media commonly show a little quantum defect, ytterbium-doped tungstates make it possible for for specially compact values. For example, a 1030-nm Yb:YAG laser would normally be pumped around 940 nm, Whilst Yb:KGW or Yb:KYW may very well be most successfully pumped all around 981 nm.
