The get bandwidth e.g. of Yb:KGW and Yb:KYW is very huge when compared with that of Yb:YAG. This allows for extensive wavelength tunability and for A great deal shorter pulse durations from mode-locked lasers. Values nicely under a hundred fs happen to be attained with passive method locking.
This exclusive characteristic of ultrafast pulses permits nonlinear optical interaction with tissue at small Over-all exposure, and drives purposes including deep-tissue multiphoton microscopy and high-precision eye surgical procedures
We current a twin-crystal Yb:KGW laserthat iscapable to function being a Q-switched oscillator with output electric power nearly 24 W and pulse duration of twenty ns,or being a regenerative amplifier with output electrical power around 21 W and pulse duration down below 200 fs right after compression of chirped pulses. Equally lasers have exceptional beam quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Screen sturdy peaks at 980 nm and 1030 nm, respectively, guaranteeing economical Electricity conversion and high overall performance in laser techniques.
Optical format of the laser with direct pumping with the radiation of semiconductor injection lasers. LD is really an IPG Photonics laser diode with fiber output in the radiation, WP is a 50 percent-wave plate, CL is really a collimating lens, FL is often a focusing lens, AE is undoubtedly an Lively element constructed from an Yb:KYW crystal, DM is really a spherical dichroic mirror, M1-M6 tend to be the cavity mirrors, OC is the output mirror, and SAM is actually a semiconductor saturable-absorber mirror.
Adhesion Examination Compliant with MIL-C-675C armed service standards, an adhesion check concerned implementing a tape that meets LT-90 specifications onto the lens movie layer. The tape was affixed fully and after that eliminated vertically. This treatment was done 3 times, resulting in no blistering or peeling.
Raman, luminescence and transmission spectra click here expose optical features owing towards the existence of thulium ions, and therefore the supplies may very well be further more examined in the scope of laser and luminescence purposes.
Spatial composition on the beam along with the corresponding depth profiles I with the output with the laser.
For tungstates, the ytterbium doping focus can be quite high devoid of substantial quenching as the changed ions have an extremely identical ion radius, and also the inter-ion distance is fairly significant.
Nonetheless, the moment Nd3+:YAG turned commercially obtainable, the fascination in CaWO4 dropped sharply. In later on decades, certain other tungstate crystals started to appeal to a great deal of notice.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison to its counterpart Yb:KGW, is really a outstanding materials that plays an essential part in laser engineering. Its Main function should be to make ultrashort pulses of light, spanning just some hundred femtoseconds.
Request RP Photonics for any tips concerning tungstate lasers, which include femtosecond lasers and large-ability lasers.
