We current a dual-crystal Yb:KGW laserthat iscapable to work for a Q-switched oscillator with output electricity around 24 W and pulse length of twenty ns,or as being a regenerative amplifier with output power as many as 21 W and pulse duration underneath 200 fs following compression of chirped pulses. Both of those lasers have fantastic beam excellent with beam parameter M2

The absorption and emission spectra of Yb:KYW Crystals Screen potent peaks at 980 nm and 1030 nm, respectively, making sure efficient energy conversion and higher efficiency in laser programs.

Ultrafast lasers, with pulse widths of some picoseconds (10−twelve s) or significantly less, allow the time resolution required in laser-excited fluorescence life span spectroscopy and imaging procedures.What's more, they supply large pulse peak powers at high repetition fees and reasonable average output powers.

Prior to the event of Nd:YAG, Nd3+:CaWO4 was a very important unusual-earth-doped laser attain medium. It was in reality Utilized in the first constantly functioning crystal laser.

PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and so are utilised as lasing components to make ultrashort (~ 100-200 fs) superior electrical power pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes operating at 981 nm supports compact laser devices.

5 mm besides the middle of your beam caustic. In order to Check out the manner matching simulation, we executed the experiment with Ng-Slash crystal oscillator, which was developed Earlier As well as in a exact situation with simulation [11]. As proven in Figure 3(b) with purple dots and line, the CW output energy is extremely depending on the place of laser crystal and also the experimental final result coincides properly with simulation end result. Being a Be aware, multimode Procedure click here happened in experiment in the event the size on the pump beam is larger sized than TEM00 cavity mode and it triggers bigger CW output energy while in the displacement location down below 3.five mm.

For tungstates, the ytterbium doping concentration can be quite superior without having sizeable quenching because the replaced ions have an exceptionally similar ion radius, along with the inter-ion length is pretty large.

By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW mainly because of the related dimensions of such chemical aspects up to a hundred% of Yb-doping may be attained.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) compared to its counterpart Yb:KGW, is really a outstanding product that performs a vital part in laser engineering. Its Main functionality is usually to create ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.

Concurrently, a shorter laser wavelength might be obtained; it can be done to operate with a quantum defect very well under one%. Being a consequence, the warmth generation is usually so tiny this partly compensates the reduce thermal conductivity.
