The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared with its counterpart Yb:KGW, is often a exceptional materials that performs an essential job in laser know-how. Its Main operate is always to generate ultrashort pulses of light, spanning only a few hundred femtoseconds.
time. Crystals in the compound melts congruently at 1007 oC, however soften crystallization of high quality crystal is unachievable resulting from period transition at ~920 oC. The very best seeded Resolution approach from
FIG. four. Autocorrelation perform of the pulse 共a兲and spectrum 共b兲of a laser with a rectangular active component for an output electric power of 700 mW. The width of
Optical layout of a laser with direct pumping Together with the radiation of semiconductor injection lasers. LD is undoubtedly an IPG Photonics laser diode with fiber output in the radiation, WP is a fifty percent-wave plate, CL can be a collimating lens, FL is often a focusing lens, AE is an active aspect made out 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.
Adhesion Test Compliant with MIL-C-675C military benchmarks, an adhesion examination involved implementing a tape that fulfills LT-90 specifications on to the lens film layer. The tape was affixed fully and afterwards eliminated vertically. This method was executed thrice, resulting in no blistering or peeling.
