The get bandwidth e.g. of Yb:KGW and Yb:KYW may be very huge as opposed with that of Yb:YAG. This allows for broad wavelength tunability and for Substantially shorter pulse durations from manner-locked lasers. Values perfectly beneath one hundred fs happen to be achieved with passive manner locking.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared to its counterpart Yb:KGW, is usually a extraordinary materials that plays a very important purpose in laser know-how. Its primary perform will be to produce ultrashort pulses of light, spanning just a few hundred femtoseconds.
We present a twin-crystal Yb:KGW laserthat iscapable to function for a Q-switched oscillator with output electricity nearly 24 W and pulse duration of 20 ns,or like a regenerative amplifier with output electric power approximately 21 W and pulse period below 200 fs right after compression of chirped pulses. Both lasers have excellent beam excellent with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Exhibit potent peaks at 980 nm and 1030 nm, respectively, making sure economical Electricity conversion and superior functionality in laser programs.
This paper describes a femtosecond laser regenerative amplifier depending on two Yb:KYW crystals with direct longitudinal pumping by impressive linear arrays of semiconductor injection lasers acquiring fiber output. To stop spectral narrowing all through amplification and the corresponding lengthening of the amplified pulse when it can be compressed, a combination of two Yb:KYW crystals ended up used, Together with the spectral maxima of the amplification shifted relative to each other and with spectral profiling with the amplified radiation.
Following air drying and subsequent cleansing that has a cotton fabric soaked in Alcoholic beverages, the movie area confirmed no signs of peeling or scratches.
Raman, luminescence and transmission spectra reveal optical functions owing to your existence of thulium ions, and so the elements may be even more studied in the scope of laser and luminescence applications.
Spatial construction on the beam as well as corresponding depth profiles I at the output of the laser.
