In useful conditions, the Yb:KYW crystal has uncovered its niche in large-electric power laser purposes as a result of its capability to make substantial Electricity ultrashort laser pulses when retaining a compact dimension. The interplay of its options �?seamless ytterbium substitution, potent absorption traits, ultrashort pulse generation and performance in Strength conversion �?positions the Yb:KYW crystal as being a cornerstone during the laser technological know-how, covering numerous fields starting from scientific investigation to industrial applications.

We existing a twin-crystal Yb:KGW laserthat iscapable to operate being a Q-switched oscillator with output electricity around 24 W and pulse duration of twenty ns,or being a regenerative amplifier with output electricity as many as 21 W and pulse period below two hundred fs after compression of chirped pulses. Each lasers have excellent beam quality with beam parameter M2
Color-coded reflectivity of a Bragg mirror to be a functionality of wavelength and angle from the incident beam.
By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW because of the identical sizes of these chemical aspects nearly 100% of Yb-doping could possibly be realized. This unique characteristic permits ytterbium to take the area of yttrium with virtually no disruption towards the crystal’s lattice.
The monoclinic crystal structures brings about a natural birefringence, assisting to avoid thermally induced polarization rotation and depolarization loss.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and are utilized as lasing components to produce ultrashort (~ 100-two hundred fs) significant electric power pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes operating at 981 nm supports compact laser units.
Spatial construction of your beam as well as corresponding intensity profiles I for the output of the laser.

On the other hand, as soon as Nd3+:YAG grew to become commercially available, the curiosity in CaWO4 dropped sharply. In later on yrs, particular other tungstate crystals started to draw in loads of attention.
The thermal conductivity of prevalent double tungstates is on the order to three–4 W/(K m) �?which isn't undesirable in contrast with other laser crystals (although various instances lower than for YAG), and rather huge in comparison with more info the thermal conductivity of common Eyeglasses.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) as compared to its counterpart Yb:KGW, is a outstanding materials that plays a crucial part in laser technological know-how. Its Most important functionality will be to crank out ultrashort pulses of light, spanning just some hundred femtoseconds.
Inquire RP Photonics for any assistance regarding tungstate lasers, including femtosecond lasers and significant-electrical power lasers.
