The obtain bandwidth e.g. of Yb:KGW and Yb:KYW is extremely large as opposed with that of Yb:YAG. This allows for large wavelength tunability and for Significantly shorter pulse durations from mode-locked lasers. Values perfectly down below one hundred fs have been achieved with passive method locking.
This exceptional characteristic of ultrafast pulses allows nonlinear optical conversation with tissue at reduced Over-all exposure, and drives apps which include deep-tissue multiphoton microscopy and substantial-precision eye surgical procedures
We current a dual-crystal Yb:KGW laserthat iscapable to operate as a Q-switched oscillator with output electrical power approximately 24 W and pulse duration of 20 ns,or for a regenerative amplifier with output ability nearly 21 W and pulse period under two hundred fs right after compression of chirped pulses. Equally lasers have superb beam good quality with beam parameter M2

This paper describes a femtosecond laser regenerative amplifier depending on two Yb:KYW crystals with immediate longitudinal pumping by strong linear arrays of semiconductor injection lasers getting fiber output. To circumvent spectral narrowing in the course of amplification and the corresponding lengthening with the amplified pulse when it's compressed, a mix of two Yb:KYW crystals had been applied, With all the spectral maxima of your amplification shifted relative to each other and with spectral profiling with the amplified radiation.
Right before the development of Nd:YAG, Nd3+:CaWO4 was an important scarce-earth-doped laser acquire more info medium. It had been in reality used in the primary consistently operating crystal laser.

five mm besides the middle on the beam caustic. In order to Verify the manner matching simulation, we done the experiment with Ng-Lower crystal oscillator, which was designed Beforehand and in a identical situation with simulation [11]. As demonstrated in Determine 3(b) with pink dots and line, the CW output electricity is highly depending on the posture of laser crystal and also the experimental consequence coincides effectively with simulation outcome. As a Observe, multimode Procedure occurred in experiment when the size of your pump beam is much larger than TEM00 cavity method and it brings about better CW output power inside the displacement area below 3.5 mm.

This tandem of attributes has far-reaching implications, specifically in the development of compact still powerfull lasers.
