The acquire bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly large as opposed with that of Yb:YAG. This permits for broad wavelength tunability and for much shorter pulse durations from method-locked lasers. Values effectively beneath 100 fs are actually accomplished with passive manner locking.
Figure seven displays the calculated dispersion compensation end result. The compressed pulse length is all over 185 fs if the duration of enter pulses is 150 fs. The discrepancy in between them will probably be drastically diminished with a longer pulse input due to the fact uncompensated significant-purchase dispersion matters considerably less for lengthier pulses. This configuration was utilized to clearly show the compressibility of our amplified pulses for the preliminary phase of our entire system. Later on we would undertake a grating-pair compressor for fantastic payment for top-purchase dispersion.
The datasets applied and/or analysed all through The existing study available from your corresponding writer on acceptable ask for.
The comparison with Eyeglasses is acceptable Considering that the massive get bandwidth allows e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
Several techniques have been adopted to solve this problem. An acousto-optical programmable dispersive filter may be utilized to modulate the seed’s spectrum to suppress the achieve-narrowing impact[
Lastly, we investigated the long-time period performances of SC technology in crystal samples beneath ideal pumping ailments at higher laser repetition premiums. In doing so, the crystal samples weren't translated and held in a stationary placement with regard towards the pump beam during the full measurement. The examples illustrating strong lengthy-phrase performances of SC generation in KGW and YAG crystals at large laser repetition charges can be identified elsewhere. A lot more especially, secure general performance of KGW crystal at two MHz pulse repetition rate less than incredibly very similar pump beam concentrating geometry was claimed recently30, While YAG crystal shown steady efficiency for several hrs at two hundred kHz pulse repetition rate Despite having quite tight focusing of the pump beam (NA=0.085)32. The very long-term efficiency tests in LSO, LYSO and YSO uncovered gradual narrowing from the SC spectra on the very long-wavelength side that happened following a specific exposure time and could be attributed to the optical degradation of those elements. For example, in LSO, the onset of spectral narrowing was observed soon after (sim twenty) minutes at a laser repetition amount of ten kHz, when at a laser repetition charge of twenty kHz, secure SC era general performance was noticed just for approximately two min.
We program to boost the heart beat Electrical power to above forty mJ in two-stage multi-move amplifiers, equivalent to a gain issue of 20. In Just about every amplifier, we may also undertake two cascaded crystals placed underneath orthogonal orientation to decrease the thermal load on Just about every crystal and compensate for that gain-narrowing result.
The two-pump laser could offer approximately one hundred twenty W power. Around 60% of the maximum pump electrical power was used inside our experiment thinking of the very low general performance of your dichroic mirrors. Less than this dual-crystal configuration, our cavity supports a one hundred W pump electricity input, as talked about in Area 2.2. Large-good quality dichroic mirrors might be applied Sooner or later, and laser pulses might be stretched to a longer pulse period.
