The gain bandwidth e.g. of Yb:KGW and Yb:KYW is quite substantial compared with that of Yb:YAG. This allows for wide wavelength tunability and for Significantly shorter pulse durations from method-locked lasers. Values effectively under one hundred fs are actually achieved with passive manner locking.
The comparison with Eyeglasses is suitable Because the large attain bandwidth will allow e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
We existing a dual-crystal Yb:KGW laserthat iscapable to operate as a Q-switched oscillator with output electricity approximately 24 W and pulse size of 20 ns,or like a regenerative amplifier with output electrical power around 21 W and pulse duration below 200 fs just after compression of chirped pulses. Each lasers have exceptional beam excellent with beam parameter M2
Shade-coded reflectivity of a Bragg mirror like a functionality of wavelength and angle with the incident beam.
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 getting fiber output. To prevent spectral narrowing during amplification as well as corresponding lengthening on the amplified pulse when it really is compressed, a combination of two Yb:KYW crystals were applied, Together with the spectral maxima from the amplification shifted relative to one another and with spectral profiling from the amplified radiation.
Just after air drying and subsequent cleaning with a cotton fabric soaked in Alcoholic beverages, the film floor confirmed no signs of peeling or scratches.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and are utilized as lasing products to crank out ultrashort (~ one hundred-two hundred fs) significant electric power pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes functioning at 981 nm supports compact laser programs.
5 mm apart from the center in the beam caustic. As a way to Examine the manner matching simulation, we done the experiment with Ng-Lower crystal oscillator, which was created Beforehand and in a exact same ailment with simulation [11]. As revealed in more info Figure three(b) with pink dots and line, the CW output electricity is very dependent on the position of laser crystal along with the experimental result coincides very well with simulation outcome. For a Be aware, multimode Procedure happened in experiment when the measurement of your pump beam is greater than TEM00 cavity method and it results in greater CW output electricity from the displacement area down below three.5 mm.

By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW as a result of equivalent dimensions of those chemical aspects approximately one hundred% of Yb-doping may be attained.
