In useful terms, the Yb:KYW crystal has identified its market in large-electrical power laser programs as a result of its capacity to produce superior Electrical power ultrashort laser pulses when retaining a compact measurement. The interplay of its options �?seamless ytterbium substitution, solid absorption traits, ultrashort pulse technology and efficiency in Electrical power conversion �?positions the Yb:KYW crystal being a cornerstone within the laser technology, masking various fields starting from scientific research to industrial apps.

The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared with its counterpart Yb:KGW, is actually a remarkable substance that performs a vital purpose in laser technological know-how. Its primary function is to deliver ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.

We current a twin-crystal Yb:KGW laserthat iscapable to function being a Q-switched oscillator with output electric power nearly 24 W and pulse duration of twenty ns,or being a regenerative amplifier with output ability nearly 21 W and pulse period under 200 fs following compression of chirped pulses. Both lasers have excellent beam high-quality with beam parameter M2

Shade-coded reflectivity of the Bragg mirror like a operate of wavelength and angle of your incident beam.

Optical layout of a laser with immediate pumping Together with the radiation of semiconductor injection lasers. LD is an IPG Photonics laser diode with fiber output on the radiation, WP is usually a half-wave plate, CL is actually a collimating lens, FL is often a concentrating lens, AE is an active component created from an Yb:KYW crystal, DM can be a spherical dichroic mirror, M1-M6 are definitely the cavity mirrors, OC could be the output mirror, and SAM is more info a semiconductor saturable-absorber mirror.

The monoclinic crystal buildings leads to a natural birefringence, assisting to stay away from thermally induced polarization rotation and depolarization reduction.

PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and they are employed as lasing materials to make ultrashort (~ 100-200 fs) significant electrical power pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes operating at 981 nm supports compact laser programs.

Tungstates are inclined to acquire high Raman coefficients (�?Raman scattering). Consequently, they will deliver significant Raman gain at moderate optical intensities. It is possible to utilize the laser crystal alone for a Raman converter.

For tungstates, the ytterbium doping focus can be very large without important quenching as the replaced ions have an extremely identical ion radius, and also the inter-ion distance is fairly significant.

By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW because of the equivalent sizes of those chemical aspects approximately a hundred% of Yb-doping could be accomplished.
