In practical conditions, the Yb:KYW crystal has identified its area of interest in large-electricity laser apps resulting from its capacity to crank out large Electrical power ultrashort laser pulses even though preserving a compact size. The interaction of its features �?seamless ytterbium substitution, powerful absorption attributes, ultrashort pulse technology and efficiency in energy conversion �?positions the Yb:KYW crystal like a cornerstone in the laser technology, covering assorted fields ranging from scientific investigation to industrial applications.
The comparison with glasses is appropriate Considering that the substantial achieve bandwidth allows e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
Femtosecond laser determined by Yb:KYW crystals with suppression of spectral narrowing in a regenerative amplifier by spectral profiling of the heart beat
FIG. four. Autocorrelation operate of the heartbeat 共a兲and spectrum 共b兲of a laser with an oblong active element for an output power of 700 mW. The width of
This paper describes a femtosecond laser regenerative amplifier dependant on two Yb:KYW crystals with direct longitudinal pumping by potent linear arrays of semiconductor injection lasers getting fiber output. To prevent spectral narrowing throughout amplification and the corresponding lengthening of the amplified pulse when it is compressed, a mix of two Yb:KYW crystals had been used, Along with the spectral maxima in the amplification shifted relative to one another and with spectral profiling in the amplified radiation.
Adhesion Exam Compliant with MIL-C-675C army specifications, an adhesion exam involved applying a tape that meets LT-90 specifications on to the lens film layer. The tape was affixed entirely after which you can eradicated vertically. This process was performed thrice, causing no blistering or peeling.
Raman, luminescence and transmission spectra reveal optical capabilities owing into the existence of thulium ions, and therefore the resources could possibly be even more analyzed while in the scope of laser and luminescence purposes.

Having said that, once Nd3+:YAG turned commercially offered, the curiosity in CaWO4 dropped sharply. In later several years, specific other tungstate crystals began to entice plenty of awareness.
The thermal conductivity of prevalent double tungstates is from the buy to three–four W/(K m) �?which is not terrible compared with other laser crystals (Despite the fact that quite a few instances a lot less than for YAG), and fairly big in comparison While using the thermal conductivity of typical glasses.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) compared to its counterpart Yb:KGW, is usually a amazing content click here that plays a very important position in laser technological innovation. Its Main functionality is usually to produce ultrashort pulses of sunshine, spanning just a few hundred femtoseconds.
Ask RP Photonics for almost any guidance relating to tungstate lasers, such as femtosecond lasers and significant-energy lasers.
