5 Easy Facts About KYW Crystal Described

The achieve bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly massive compared with that of Yb:YAG. This enables for huge wavelength tunability and for much shorter pulse durations from mode-locked lasers. Values very well underneath 100 fs are actually achieved with passive method locking.

This exclusive characteristic of ultrafast pulses permits nonlinear optical interaction with tissue at minimal General publicity, and drives applications such as deep-tissue multiphoton microscopy and superior-precision eye medical procedures

time. Crystals in the compound melts congruently at 1007 oC, on the other hand melt crystallization of top of the range crystal is extremely hard resulting from phase changeover at ~920 oC. The highest seeded Option system from

If you're attempting to obtain This page making use of an nameless Private/Proxy network, you should disable that and take a look at accessing web page once more.

Optical format of the laser with immediate pumping Along with the radiation of semiconductor injection lasers. LD is an IPG Photonics laser diode with fiber output on the radiation, WP is often a half-wave plate, CL is really a collimating lens, FL is a focusing lens, AE is undoubtedly an active aspect produced from an Yb:KYW crystal, DM is actually a spherical dichroic mirror, M1-M6 will be the cavity mirrors, OC would be the output mirror, and SAM is a semiconductor saturable-absorber mirror.

Adhesion Take a look at Compliant with MIL-C-675C military specifications, an adhesion test concerned making use of a tape that satisfies LT-ninety technical specs on to the lens movie layer. The tape was affixed totally then taken off vertically. This technique was executed thrice, causing no blistering or peeling.

Spatial composition of your beam and the corresponding depth profiles I on the output of the laser.

... at fifty percent-top were being produced in a grasp oscillator with selfsynchronization of the axial modes, explained in our previously article. 21 The new edition from the laser, as opposed to that described inside our earlier report, utilised an Yb:KYW crystal using an N pcut (optical axis N p in the index ellipsoid was parallel to your propagation course in the laser radiation), Together with the polarization from the generated radiation directed alongside the N m axis.

... Not simply the situation of crystal inside the cavity but will also the get more info amplification axis of crystal influences the laser Procedure considerably, as the absorption and emission cross sections in the crystal are really unique according to the orientation from the crystal.
