In sensible conditions, the Yb:KYW crystal has uncovered its area of interest in large-energy laser purposes resulting from its capability to deliver substantial Power ultrashort laser pulses whilst maintaining a compact dimensions. The interaction of its attributes �?seamless ytterbium substitution, solid absorption traits, ultrashort pulse era and effectiveness in Electrical power conversion �?positions the Yb:KYW crystal as being a cornerstone while in the laser technology, covering various fields ranging from scientific investigation to industrial purposes.
The comparison with glasses is appropriate Considering that the substantial get bandwidth permits e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
We present a dual-crystal Yb:KGW laserthat iscapable to operate as a Q-switched oscillator with output energy around 24 W and pulse length of 20 ns,or as a regenerative amplifier with output power up to 21 W and pulse period underneath 200 fs following compression of chirped pulses. The two lasers have excellent beam quality with beam parameter M2
Shade-coded reflectivity of the Bragg mirror as a purpose of wavelength and angle with the incident beam.
Optical structure of the laser with direct pumping While using the radiation of semiconductor injection lasers. LD is undoubtedly an IPG Photonics laser diode with fiber output on the radiation, WP is often a half-wave plate, CL is actually a collimating lens, FL is often a focusing lens, AE is undoubtedly an active factor comprised of an Yb:KYW crystal, DM is actually a spherical dichroic mirror, M1-M6 are definitely the cavity mirrors, OC may be the output mirror, and SAM is often a semiconductor saturable-absorber mirror.
The monoclinic crystal constructions results in a all-natural birefringence, assisting to stay clear of thermally induced polarization rotation and depolarization decline.
Raman, luminescence and transmission spectra expose optical capabilities owing into the existence of thulium ions, and therefore the supplies could possibly be even more analyzed in the scope of laser and luminescence applications.
A higher brightnessQ-switched oscillator and regenerative amplifier according to a twin-crystal Yb:KGW laser

Significant-energy repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical applications
Whilst ytterbium-doped laser get media commonly show a small quantum defect, ytterbium-doped tungstates enable for specifically smaller values. By way of example, a 1030-nm Yb:YAG laser would Usually be pumped all-around 940 nm, Whilst Yb:KGW or Yb:KYW may be most successfully pumped close to 981 nm.
This tandem of attributes has significantly-achieving implications, specifically in the development of compact nonetheless powerfull lasers.
