In functional phrases, the Yb:KYW crystal has identified its niche in high-ability laser purposes as a consequence of its power to make large Power ultrashort laser pulses while protecting a compact dimensions. The interplay of its attributes �?seamless ytterbium substitution, potent absorption features, ultrashort pulse era and efficiency in energy conversion �?positions the Yb:KYW crystal as a cornerstone from the laser know-how, covering numerous fields ranging from scientific investigate to industrial programs.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison to its counterpart Yb:KGW, is often a outstanding content that performs a crucial function in laser technological know-how. Its Major perform is usually to crank out ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
We present a twin-crystal Yb:KGW laserthat iscapable to operate to be a Q-switched oscillator with output power approximately 24 W and pulse duration of twenty ns,or like a regenerative amplifier with output electric power up to 21 W and pulse period under 200 fs soon after compression of chirped pulses. Both lasers have superb beam high quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Exhibit robust peaks at 980 nm and 1030 nm, respectively, making certain effective Strength conversion and large effectiveness in laser techniques.
Optical structure of a laser with immediate pumping Along with the radiation of semiconductor injection lasers. LD is undoubtedly an IPG Photonics laser diode with fiber output on the radiation, WP is really a 50 percent-wave plate, CL can be a collimating lens, FL is really a concentrating lens, AE is surely an Energetic ingredient made out of an Yb:KYW crystal, DM is usually a spherical dichroic mirror, M1-M6 are definitely the cavity mirrors, OC is the output mirror, and SAM is often a semiconductor saturable-absorber mirror.
The monoclinic crystal buildings brings about a organic birefringence, assisting to avoid thermally induced polarization rotation and depolarization decline.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and are utilized as lasing products to produce ultrashort (~ one hundred-two hundred fs) superior electric power pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes functioning at 981 nm supports compact laser units.
A higher brightnessQ-switched oscillator and regenerative amplifier dependant on a dual-crystal Yb:KGW laser
... at half-top were produced in a grasp oscillator with selfsynchronization with the axial modes, described within our before post. 21 The new version of your laser, in contrast to that explained inside our earlier write-up, applied an Yb:KYW crystal with an N pcut (optical axis N p on the index ellipsoid was parallel into the propagation direction in the laser radiation), While using the polarization of the generated radiation directed alongside the N m axis.
By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW due to related sizes of these chemical features as many as one hundred% of Yb-doping might be achieved.
The thermal conductivity of common double tungstates is of your buy website to 3–four W/(K m) �?which is not bad as opposed with other laser crystals (While numerous times less than for YAG), and rather big in comparison with the thermal conductivity of standard Eyeglasses.
Li2WO4-WO3 flux was correctly applied reducing the growth temperature below 900 oC. In keeping with solitary crystal x-ray measurements, the crystal corresponds for the P2/n Room group.
