We present a dual-crystal Yb:KGW laserthat iscapable to function being a Q-switched oscillator with output ability as much as 24 W and pulse length of 20 ns,or as being a regenerative amplifier with output electricity as much as 21 W and pulse length under 200 fs right after compression of chirped pulses. Each lasers have exceptional beam high quality with beam parameter M2

The absorption and emission spectra of Yb:KYW Crystals display robust peaks at 980 nm and 1030 nm, respectively, making certain productive Electricity conversion and superior performance in laser systems.

Optical structure of a laser with immediate pumping While using the radiation of semiconductor injection lasers. LD can be an IPG Photonics laser diode with fiber output from the radiation, WP is actually a half-wave plate, CL is a collimating lens, FL can be a concentrating lens, AE is surely an Lively element made out of an Yb:KYW crystal, DM is a spherical dichroic mirror, M1-M6 tend to be the cavity mirrors, OC is the output mirror, and SAM is actually a semiconductor saturable-absorber mirror.

Adhesion Test Compliant with MIL-C-675C military expectations, an adhesion exam concerned making use of a tape that fulfills LT-ninety specs on to the lens movie layer. The tape was affixed fully after which taken off vertically. This treatment was done 3 times, resulting in no blistering or peeling.

Raman, luminescence and transmission spectra expose optical options owing to the existence of thulium ions, and therefore the supplies could possibly be more examined in the scope of laser and luminescence KYW Crystal applications.

Tungstates tend to own significant Raman coefficients (�?Raman scattering). Therefore, they're able to make sizeable Raman gain at moderate optical intensities. It is possible to utilize the laser crystal alone to be a Raman converter.

For tungstates, the ytterbium doping focus can be very significant with out sizeable quenching since the changed ions have a very equivalent ion radius, plus the inter-ion length is fairly large.

By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW as a result of equivalent sizes of such chemical aspects approximately 100% of Yb-doping can be accomplished.

Concurrently, a shorter laser wavelength might be obtained; it can be done to function with a quantum defect very well below 1%. To be a consequence, the heat technology might be so small this partly compensates the lower thermal conductivity.
