The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared with its counterpart Yb:KGW, is usually a remarkable materials that plays an essential part in laser technological innovation. Its Most important purpose should be to deliver ultrashort pulses of sunshine, spanning just some hundred femtoseconds.

We existing a twin-crystal Yb:KGW laserthat iscapable to work to be a Q-switched oscillator with output power as much as 24 W and pulse length of twenty ns,or being a regenerative amplifier with output energy around 21 W and pulse length below two hundred fs after compression of chirped pulses. Each lasers have superb beam top quality with beam parameter M2

Colour-coded reflectivity of a Bragg mirror being a perform of wavelength and angle with the incident beam.

Ultrafast lasers, with pulse widths of a few picoseconds (ten−twelve s) or significantly less, enable enough time resolution demanded in laser-excited fluorescence life time spectroscopy and imaging methods.Additionally, they deliver significant pulse peak powers at large repetition rates and moderate ordinary output powers.

Adhesion Take a look at Compliant with MIL-C-675C armed service specifications, an adhesion take a look at associated implementing a tape that satisfies LT-ninety technical specs onto the lens film layer. The tape was affixed entirely and then eliminated vertically. This read more method was done 3 times, leading to no blistering or peeling.

Raman, luminescence and transmission spectra expose optical capabilities owing to the presence of thulium ions, and thus the components may be even further analyzed inside the scope of laser and luminescence applications.

Spatial composition of your beam and the corresponding depth profiles I for the output with the laser.

For tungstates, the ytterbium doping concentration can be quite superior without having sizeable quenching because the replaced ions have an exceedingly comparable ion radius, plus the inter-ion length is relatively huge.

By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW mainly because of the identical sizes of such chemical factors nearly one hundred% of Yb-doping could possibly be attained.

Li2WO4-WO3 flux was effectively applied lowering the growth temperature under 900 oC. In keeping with one crystal x-ray measurements, the crystal corresponds into the P2/n space team.

Concurrently, a shorter laser wavelength is often acquired; it is possible to function using a quantum defect well underneath 1%. For a consequence, the heat era may be so smaller that this partly compensates the decreased thermal conductivity.
