In useful phrases, the Yb:KYW crystal has identified its market in superior-energy laser applications as a result of its ability to generate high Electrical power ultrashort laser pulses when keeping a compact measurement. The interplay of its options �?seamless ytterbium substitution, solid absorption attributes, ultrashort pulse generation and effectiveness in Electricity conversion �?positions the Yb:KYW crystal as being a cornerstone during the laser technological know-how, covering diverse fields starting from scientific analysis to industrial purposes.
This unique characteristic of ultrafast pulses enables nonlinear optical interaction with tissue at reduced Total publicity, and drives apps for example deep-tissue multiphoton microscopy and substantial-precision eye surgical treatment
We current a dual-crystal Yb:KGW laserthat iscapable to work for a Q-switched oscillator with output electricity nearly 24 W and pulse length of twenty ns,or for a regenerative amplifier with output electrical power approximately 21 W and pulse period below two hundred fs soon after compression of chirped pulses. Each lasers have outstanding beam high quality with beam parameter M2
Shade-coded reflectivity of the Bragg mirror as a functionality of wavelength and angle of your incident beam.
By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW a result of the equivalent measurements of those chemical aspects up to 100% of Yb-doping could possibly be accomplished. This special attribute permits ytterbium to take the position of yttrium with practically no disruption towards the crystal’s lattice.
Just before the event of Nd:YAG, Nd3+:CaWO4 was a vital uncommon-earth-doped laser achieve medium. It absolutely was actually Utilized in the 1st constantly running crystal laser.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison with its counterpart Yb:KGW, can be a impressive substance that performs a crucial part in laser engineering. Its Main function will be to make ultrashort pulses of light, spanning just some hundred femtoseconds.
Concurrently, a shorter laser wavelength is usually acquired; it is feasible to work that has a quantum defect perfectly below one%. For a consequence, the warmth technology is often so smaller this partly compensates the reduce thermal conductivity.
