Making use of our advertising bundle, you could Screen your symbol, additional under your products description, and these will been observed by quite a few photonics experts.
This distinctive characteristic of ultrafast pulses enables nonlinear optical interaction with tissue at minimal Total exposure, and drives apps for instance deep-tissue multiphoton microscopy and superior-precision eye surgery
The Yb:KYW crystal’s proficiency in light absorption at about 981 nm tends to make the crystal well suited for diode pumping. It's further Increased by its extraordinary effectiveness in this process, coupled with its reduced quantum defect.

This paper describes a femtosecond laser regenerative amplifier based on two Yb:KYW crystals with immediate longitudinal pumping by highly effective linear arrays of semiconductor injection lasers having fiber output. To stop spectral narrowing all through amplification as well as corresponding lengthening with the amplified pulse when it is actually compressed, a combination of two Yb:KYW crystals have been used, Using the spectral maxima of the amplification shifted relative to each other and with spectral profiling from the amplified radiation.
Soon after air drying and subsequent cleansing that has a cotton cloth soaked in alcohol, the movie floor confirmed no signs of peeling or scratches.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and they are utilized as lasing materials to produce ultrashort (~ one hundred-two hundred fs) superior power pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact laser methods.
A superior brightnessQ-switched oscillator and regenerative amplifier determined by a twin-crystal Yb:KGW laser
... at fifty percent-top had been produced in a grasp oscillator with selfsynchronization of your axial modes, described within our before post. 21 The new edition of your laser, as opposed to that explained inside our get more info earlier report, made use of an Yb:KYW crystal with the N pcut (optical axis N p with the index ellipsoid was parallel to the propagation path on the laser radiation), with the polarization from the produced radiation directed alongside the N m axis.
Superior-energy repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical apps

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison to its counterpart Yb:KGW, is really a outstanding material that performs a significant position in laser technological innovation. Its Principal perform would be to generate ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
Talk to RP Photonics for almost any guidance about tungstate lasers, like femtosecond lasers and high-electric power lasers.
