For many apps, tungstates provide a combination of various handy Houses. In particular for passive mode locking, ytterbium-doped double tungstates will often be exceptional to other media with regard to The mix of high get bandwidth, big cross-sections, and relatively very good thermal Attributes �?Despite the fact that in Just about every specific willpower much better elements might be discovered.
Together with its use as being a Raman crystal, KGW is usually Utilized in other optical purposes, including in laser systems and for a scintillator in health care imaging.
The monoclinic crystal constructions leads to a organic birefringence, assisting to keep away from thermally induced polarization rotation and depolarization reduction.
Amplified pulses with an Electrical power earlier mentioned 2.five mJ might be expected by applying an increased pump ability towards the regenerative amplifier and making it work within the saturation level. The laser fluence of ~1 J/cm2 over the dichroic mirrors is believed to be down below the hurt threshold of superior-high-quality dielectric-coated mirrors.

Dynamic expression of genes encoding subunits of inward rectifier potassium (Kir) channels inside the yellow fever mosquito Aedes aegypti.
So, with an additional enhancement within our regenerative amplifier, 2 mJ compressed pulses may be expected, devoid of detrimental any component within our compressor.

The Martinez stretcher stretched the seed pulses to ~250 ps with 1600 grooves/mm grating. The input with the stretcher (incident angle: 52°) and that from the compressor incident in the grating were with the same side; hence, a slight angular tuning in the grating may very well be created to obtain the very best compression consequence. From the compressor, the enter angle about the grating and the space amongst the interpretation stage (S1) as well as transmission grating (TG) have been designed to compensate with the stretcher dispersion and all dispersion introduced with the materials.
KGW has a powerful Raman spectrum that extends from the ultraviolet on the in close proximity to infrared, rendering it handy for A selection of applications. The crystal can be employed like a reference product for Raman spectroscopy, as well as a sample for finding out Raman scattering during the reliable point out.
Determine four Beam radius variation on The 2 crystals while altering the focal size on the thermal lensing outcome.
]. The twin-crystal configuration lowers the thermal load on Every single crystal whilst preserving a high gain, and facilitates the compensation of each’s thermal lensing impact. Hence, the laser cavity can get the job done with a big steadiness selection around the thermal lensing influence variation.
