The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, as compared to its counterpart Yb:KGW, is really a exceptional content that plays a vital purpose in laser technology. Its Main function should be to deliver ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.
We present a dual-crystal Yb:KGW laserthat iscapable to operate like a Q-switched oscillator with output electricity up to 24 W and pulse size of 20 ns,or like a regenerative amplifier with output power up to 21 W and pulse period under two hundred fs just after compression of chirped pulses. The two lasers have excellent beam top quality with beam parameter M2
Colour-coded reflectivity of a Bragg mirror for a functionality of wavelength and angle of the incident beam.
Optical structure of a laser with immediate pumping Together with the radiation of semiconductor injection lasers. LD is definitely an IPG Photonics laser diode with fiber output of your radiation, WP is often a half-wave plate, CL is often a collimating lens, FL is really a concentrating lens, AE is definitely an Energetic ingredient produced from an Yb:KYW crystal, DM is really a spherical dichroic mirror, M1-M6 are the cavity mirrors, OC would be the output mirror, and SAM is usually a semiconductor saturable-absorber mirror.
The monoclinic crystal buildings brings about a pure birefringence, assisting to avoid thermally induced polarization rotation and depolarization decline.
Raman, luminescence and transmission spectra reveal optical capabilities owing to the presence of thulium ions, and therefore the resources may very well be further more examined from the scope of laser and luminescence apps.
Spatial structure of the beam as well as corresponding depth profiles I for the output on the laser.

However, after Nd3+:YAG grew to become commercially readily available, the interest in CaWO4 dropped sharply. In later several years, sure other tungstate crystals began to attract plenty of consideration.
As a result of Beforehand detected destructive behavior which originated within the community you're applying, you should request unblock to web-site.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared to its counterpart Yb:KGW, is usually a extraordinary substance that plays a significant purpose in laser technological innovation. Its Principal purpose is usually to crank out ultrashort pulses click here of light, spanning just a couple hundred femtoseconds.
