We current a dual-crystal Yb:KGW laserthat iscapable to work being a Q-switched oscillator with output electrical power as much as 24 W and pulse size of twenty ns,or being a regenerative amplifier with output energy as many as 21 W and pulse length beneath two hundred fs soon after compression of chirped pulses. The two lasers have outstanding beam high quality with beam parameter M2
Color-coded reflectivity of a Bragg mirror like a operate of wavelength and angle with the incident beam.
Ultrafast lasers, with pulse widths of a few picoseconds (ten−12 s) or fewer, help enough time resolution necessary in laser-thrilled fluorescence lifetime spectroscopy and imaging tactics.Additionally, they deliver large pulse peak powers at large repetition fees and average regular output powers.
The monoclinic crystal structures ends in a natural birefringence, assisting to keep away from thermally induced polarization rotation and depolarization loss.

A superior brightnessQ-switched oscillator and regenerative amplifier depending on a dual-crystal Yb:KGW laser
For tungstates, the ytterbium doping focus can be extremely high with no significant quenching because the changed ions have an extremely identical ion radius, and the inter-ion distance is relatively significant.
High-electric power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical apps
The thermal conductivity of typical double tungstates is of your get to 3–four W/(K m) �?which is not undesirable when compared with other laser crystals (although quite a few moments less than for YAG), and pretty massive in contrast Together with the thermal conductivity KYW Crystal of common glasses.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared to its counterpart Yb:KGW, is actually a extraordinary material that performs a crucial role in laser technological know-how. Its Key operate would be to create ultrashort pulses of light, spanning just some hundred femtoseconds.
