The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, compared to its counterpart Yb:KGW, is actually a remarkable materials that performs an important purpose in laser engineering. Its Most important operate is always to make ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
We existing a twin-crystal Yb:KGW laserthat iscapable to function being a Q-switched oscillator with output energy as many as 24 W and pulse duration of 20 ns,or being a regenerative amplifier with output ability nearly 21 W and pulse length under two hundred fs soon after compression of chirped pulses. Equally lasers have fantastic beam good quality with beam parameter M2
Coloration-coded reflectivity of a Bragg mirror to be a function of wavelength and angle of your incident beam.
Optical layout of a laser with direct pumping With all the radiation of semiconductor injection lasers. LD is surely an IPG Photonics laser diode with fiber output in the radiation, WP can be a fifty percent-wave plate, CL is actually a collimating lens, FL is actually a focusing lens, AE is an active ingredient constructed from an Yb:KYW crystal, DM is really 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.
The monoclinic crystal structures results in a all-natural birefringence, helping to steer clear of thermally induced polarization rotation and depolarization loss.
FIG. one. Optical format of a laser with direct pumping Using the radiation of semiconductor injection lasers. LD is definitely an IPG Photonics laser diode with fiber output
Tungstates have a tendency to own significant Raman coefficients (�?Raman scattering). As a result, they will deliver major Raman attain at reasonable optical intensities. It is feasible to use the laser crystal itself being a Raman converter.

Substantial-ability repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical purposes
The thermal conductivity of prevalent double tungstates is with the get to 3–4 W/(K m) �?which isn't lousy in contrast with other laser crystals (Whilst several occasions fewer than for YAG), and rather massive in contrast with the thermal conductivity of regular glasses.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) as compared to its counterpart Yb:KGW, is usually a extraordinary substance that performs a crucial part in laser engineering. Its Main function should be to crank out ultrashort pulses of light, spanning just a few hundred femtoseconds.
