The gain bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly significant 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 beneath 100 fs are already achieved with passive manner locking.

This one of a kind attribute of ultrafast pulses enables nonlinear optical conversation with tissue at minimal overall publicity, and drives apps like deep-tissue multiphoton microscopy and high-precision eye operation

We existing a twin-crystal Yb:KGW laserthat iscapable to function for a Q-switched oscillator with output ability up to 24 W and pulse length of twenty ns,or to be a regenerative amplifier with output power approximately 21 W and pulse length under 200 fs immediately after compression of chirped pulses. Both equally lasers have great beam good quality with beam parameter M2

Coloration-coded reflectivity of the Bragg mirror as a perform of wavelength and angle in the incident beam.

This paper describes a femtosecond laser regenerative amplifier based upon two Yb:KYW crystals with direct longitudinal pumping by highly effective linear arrays of semiconductor injection lasers possessing fiber output. To stop spectral narrowing all through amplification along with the corresponding lengthening of your amplified pulse when it truly is compressed, a combination of two Yb:KYW crystals were being utilised, With all the spectral maxima of the amplification shifted relative to each other and with spectral profiling of the amplified radiation.

Before the development of Nd:YAG, Nd3+:CaWO4 was an important rare-earth-doped laser obtain medium. It absolutely was in fact Utilized in the 1st continuously operating crystal laser.

Raman, luminescence and transmission spectra expose optical functions owing to the presence of thulium ions, and so the products may be even further examined within the scope of laser and luminescence apps.

A higher brightnessQ-switched oscillator and regenerative amplifier determined by a twin-crystal Yb:KGW laser

For tungstates, the ytterbium doping focus can be very large without the need of significant quenching because the replaced ions have an exceptionally identical ion radius, and also the inter-ion distance is relatively large.

Large-electric power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping get more info for technological and biomedical purposes

Simultaneously, a shorter laser wavelength can be received; it is possible to function with a quantum defect very well beneath one%. Being a consequence, the warmth generation is often so little that this partly compensates the lessen thermal conductivity.
