The get bandwidth e.g. of Yb:KGW and Yb:KYW is quite big 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 effectively under 100 fs are already reached with passive manner locking.
That is a preview of membership content, log in by way of an establishment to check access. Accessibility this information
We present a twin-crystal Yb:KGW laserthat iscapable to function as being a Q-switched oscillator with output power nearly 24 W and pulse size of twenty ns,or being a regenerative amplifier with output energy as many as 21 W and pulse duration underneath 200 fs following compression of chirped pulses. Each lasers have fantastic beam good quality with beam parameter M2
Colour-coded reflectivity of a Bragg mirror as being a perform of wavelength and angle in the incident beam.
Ultrafast lasers, with pulse widths of some picoseconds (10−twelve s) or considerably less, allow some time resolution necessary in laser-excited fluorescence life time spectroscopy and imaging methods.What's more, they provide significant pulse peak powers at higher repetition premiums and moderate common output powers.
Following air drying and subsequent cleaning that has a cotton fabric soaked in alcohol, the film surface showed no signs of peeling or scratches.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and so are made use of as lasing supplies to produce ultrashort (~ one hundred-200 fs) higher electric power pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes running at 981 nm supports compact laser programs.
A higher brightnessQ-switched oscillator and regenerative amplifier depending on a dual-crystal Yb:KGW laser

By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW because of the similar dimensions KYW Crystal of such chemical things around 100% of Yb-doping can be realized.
The thermal conductivity of widespread double tungstates is in the get to 3–four W/(K m) �?which is not lousy as opposed with other laser crystals (Despite the fact that a number of situations under for YAG), and fairly massive as opposed Together with the thermal conductivity of regular glasses.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared to its counterpart Yb:KGW, is often a amazing substance that plays an essential role in laser technology. Its Most important functionality should be to make ultrashort pulses of light, spanning just a couple hundred femtoseconds.
Ask RP Photonics for almost any suggestions regarding tungstate lasers, including femtosecond lasers and significant-electrical power lasers.
