The attain bandwidth e.g. of Yb:KGW and Yb:KYW is quite substantial compared with that of Yb:YAG. This allows for vast wavelength tunability and for Substantially shorter pulse durations from manner-locked lasers. Values well below 100 fs are already reached with passive mode locking.
This exceptional characteristic of ultrafast pulses permits nonlinear optical interaction with tissue at low In general exposure, and drives purposes for example deep-tissue multiphoton microscopy and higher-precision eye surgical procedure
The Yb:KYW crystal’s proficiency in light absorption at around 981 nm can make the crystal well matched for diode pumping. It truly is further more enhanced by its exceptional effectiveness in this process, coupled with its minimal quantum defect.
Color-coded reflectivity of a Bragg mirror like a operate of wavelength and angle with the incident beam.
Ultrafast lasers, with pulse widths of some picoseconds (ten−twelve s) or considerably less, permit time resolution needed in laser-thrilled fluorescence life span spectroscopy and imaging approaches.What's more, they supply substantial pulse peak powers at large repetition rates and reasonable normal output powers.
The monoclinic crystal constructions leads to a organic birefringence, helping to avoid thermally induced polarization rotation and depolarization decline.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and are made use of as lasing products to make ultrashort (~ 100-two hundred fs) substantial electricity pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes operating get more info at 981 nm supports compact laser devices.
Tungstates are likely to possess substantial Raman coefficients (�?Raman scattering). Thus, they can produce considerable Raman obtain at reasonable optical intensities. It is feasible to use the laser crystal itself as a Raman converter.
... at half-top have been generated in a master oscillator with selfsynchronization of the axial modes, explained within our earlier posting. 21 The new version from the laser, unlike that explained in our previously post, made use of an Yb:KYW crystal using an N pcut (optical axis N p of the index ellipsoid was parallel to your propagation path of your laser radiation), Together with the polarization of the produced radiation directed together the N m axis.
Higher-electric power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical applications
The thermal conductivity of widespread double tungstates is from the get to 3–four W/(K m) �?which isn't undesirable compared with other laser crystals (While numerous situations under for YAG), and quite huge when compared Using the thermal conductivity of normal Eyeglasses.
