The acquire bandwidth e.g. of Yb:KGW and Yb:KYW is rather large in contrast with that of Yb:YAG. This enables for huge wavelength tunability and for much shorter pulse durations from mode-locked lasers. Values effectively underneath a hundred fs have been accomplished with passive mode locking.

This unique characteristic of ultrafast pulses permits nonlinear optical interaction with tissue at low All round publicity, and drives apps such as deep-tissue multiphoton microscopy and substantial-precision eye surgery

time. Crystals with the compound melts congruently at 1007 oC, even so melt crystallization of top of the range crystal is extremely hard due to period transition at ~920 oC. The highest seeded Option approach from

FIG. four. Autocorrelation operate of the pulse 共a兲and spectrum 共b兲of a laser with an oblong active aspect for an output energy of seven hundred mW. The width of

This paper describes a femtosecond laser regenerative amplifier depending on two Yb:KYW crystals with direct longitudinal pumping by potent linear arrays of semiconductor injection lasers having fiber output. To circumvent spectral narrowing all through amplification plus the corresponding lengthening on the amplified pulse when it really is compressed, a mix of two Yb:KYW crystals ended up employed, Along with the spectral maxima from the amplification shifted relative to one another and with spectral read more profiling from the amplified radiation.

Just after air drying and subsequent cleaning that has a cotton fabric soaked in Liquor, the movie area showed no signs of peeling or scratches.

PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and therefore are utilized as lasing materials to deliver ultrashort (~ one hundred-200 fs) significant electricity pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes functioning at 981 nm supports compact laser programs.

A substantial brightnessQ-switched oscillator and regenerative amplifier based upon a dual-crystal Yb:KGW laser
