Earlier operate showed that the dual-crystal configuration can be utilized to compensate for the thermal lensing outcome[
While ytterbium-doped laser achieve media usually exhibit a small quantum defect, ytterbium-doped tungstates allow for specially tiny values. By way of example, a 1030-nm Yb:YAG laser would Usually be pumped all-around 940 nm, While Yb:KGW or Yb:KYW could possibly be most proficiently pumped around 981 nm.
For some purposes, tungstates present a combination of different handy Attributes. Specifically for passive mode locking, ytterbium-doped double tungstates are often superior to other media concerning The mix of superior achieve bandwidth, big cross-sections, and comparatively excellent thermal Qualities �?even though in Just about every specific self-control better resources may very well be discovered.
Determine 7 exhibits the calculated dispersion payment final result. The compressed pulse length is all around 185 fs when the length of input pulses is one hundred fifty fs. The discrepancy between them might be drastically decreased with a longer pulse enter simply because uncompensated large-buy dispersion matters fewer for lengthier pulses. This configuration was utilized to show the compressibility of our amplified pulses for the preliminary section of our entire technique. Sooner or later we might undertake a grating-pair compressor for wonderful payment for top-get dispersion.
The datasets utilized and/or analysed during The existing study available within the corresponding writer on reasonable ask for.
For tungstates, the ytterbium doping concentration can be extremely significant with no important quenching because the changed ions have an incredibly identical ion radius, plus the inter-ion distance is comparatively massive.

Comparison of spectral Electrical power densities of supercontinua produced in the conditions of optimal pumping during the investigated materials.
Despite the fact that BGO and LT created the narrowest SC spectra (marginally lower than 1.five optical octaves), they might be viewed as pretty eye-catching nonlinear supplies for broadband SC era with pumping at more time laser wavelengths. Owing to its big nonlinearity, get more info BGO exhibited the lowest SC technology threshold (seventy eight nJ) One of the investigated products, that is 25 % lower than in KGW and could be regarded as exceptional nonlinear materials for very small-threshold SC era. The noticed stable and durable injury-totally free functionality of BGO and GGG at 200 kHz pulse repetition amount indicates that these nonlinear materials have a possible for SC technology at even greater, MHz, repetition fees. In addition, these products give SC radiation with an excellent set of parameters which are important for purposes in significant pace spectroscopy and imaging that use bulk-generated SC, see e.g.seventeen,eighteen,19,twenty.
The 2-pump laser could provide up to one hundred twenty W energy. Close to 60% of the utmost pump electrical power was used in our experiment thinking of the lower overall performance with the dichroic mirrors. Under this dual-crystal configuration, our cavity supports a one hundred W pump power input, as reviewed in Portion 2.2. Significant-quality dichroic mirrors is going to be applied Down the road, and laser pulses will be stretched to an extended pulse length.
The Martinez stretcher stretched the seed pulses to ~250 ps with 1600 grooves/mm grating. The enter with the stretcher (incident angle: fifty two°) and that from the compressor incident at the grating were from the exact aspect; hence, a slight angular tuning of your grating may very well be created to obtain the ideal compression final result. In the compressor, the enter angle on the grating and the distance in between the translation phase (S1) as well as transmission grating (TG) were made to compensate for your stretcher dispersion and all dispersion introduced via the products.
