In simple conditions, the Yb:KYW crystal has uncovered its specialized niche in high-power laser applications because of its ability to generate high Electrical power ultrashort laser pulses though keeping a compact measurement. The interaction of its characteristics �?seamless ytterbium substitution, robust absorption traits, ultrashort pulse technology and effectiveness in energy conversion �?positions the Yb:KYW crystal to be a cornerstone while in the laser engineering, masking varied fields starting from scientific investigate to industrial apps.
The comparison with glasses is appropriate Considering that the huge obtain bandwidth permits e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
We present a dual-crystal Yb:KGW laserthat iscapable to operate as being a Q-switched oscillator with output electrical power approximately 24 W and pulse size of 20 ns,or for a regenerative amplifier with output ability nearly 21 W and pulse duration below two hundred fs just after compression of chirped pulses. Both of those lasers have fantastic beam high-quality with beam parameter M2
Color-coded reflectivity of a Bragg mirror like a operate of wavelength and angle of your incident beam.
Optical format of the laser with direct pumping Using the radiation of semiconductor injection lasers. LD is an IPG Photonics laser diode with fiber output with the radiation, WP is actually a 50 %-wave plate, CL can be a collimating lens, FL is a concentrating lens, AE is an Energetic aspect produced from an Yb:KYW crystal, DM is often a spherical dichroic mirror, M1-M6 would be the cavity mirrors, OC will be the output mirror, and SAM is often a semiconductor saturable-absorber mirror.
Adhesion Check Compliant with MIL-C-675C armed forces expectations, an adhesion examination concerned applying a tape that satisfies LT-90 technical specs onto the lens film layer. The tape was affixed fully and then taken off vertically. This treatment was carried out thrice, leading to no blistering or peeling.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and are used as lasing components to create ultrashort (~ 100-two hundred fs) substantial electricity pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes running at 981 nm supports compact laser techniques.
Spatial framework in the beam along with the corresponding intensity profiles I in the output from the laser.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison to its counterpart Yb:KGW, can be a exceptional materials that performs a very important job in laser technological innovation. Its Most important purpose is usually to deliver ultrashort pulses of light, spanning just a couple hundred femtoseconds.
