Utilizing our advertising and marketing package deal, you'll be able to display your brand, further under your product description, and these will been observed by many photonics experts.

The comparison with glasses is appropriate For the reason that significant attain bandwidth will allow e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.

We existing a twin-crystal Yb:KGW laserthat iscapable to operate as being a Q-switched oscillator with output power around 24 W and pulse duration of 20 ns,or as a regenerative amplifier with output ability nearly 21 W and pulse length beneath two hundred fs just after compression of chirped pulses. Each lasers have fantastic beam good quality with beam parameter M2

The absorption and emission spectra of Yb:KYW Crystals Display screen strong peaks at 980 nm and 1030 nm, respectively, ensuring successful energy conversion and high efficiency in laser programs.

By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW mainly because of the equivalent measurements of such chemical elements up to one hundred% of Yb-doping may very well be achieved. This special characteristic permits ytterbium to take the area of yttrium with almost no disruption to your crystal’s lattice.

After air drying and subsequent cleaning with a cotton cloth soaked in Alcoholic beverages, the film floor confirmed no signs of peeling or scratches.

Tungstates are likely to own substantial Raman coefficients (�?Raman scattering). As a result, they might generate substantial Raman attain at average optical intensities. It can be done to use the laser crystal itself as being a Raman converter.

For tungstates, the ytterbium doping focus can be very large without the need of substantial quenching since the click here replaced ions have a really equivalent ion radius, plus the inter-ion length is fairly significant.

Even so, when Nd3+:YAG turned commercially available, the curiosity in CaWO4 dropped sharply. In afterwards years, specific other tungstate crystals began to catch the attention of lots of awareness.

On account of Formerly detected destructive behavior which originated within the community you happen to be making use of, please ask for unblock to web site.

This tandem of characteristics has much-achieving implications, especially in the development of compact yet powerfull lasers.
