KYW Crystal - An Overview
Blog Article
In sensible phrases, the Yb:KYW crystal has discovered its niche in substantial-ability laser applications due to its power to make large Strength ultrashort laser pulses while preserving a compact size. The interplay of its capabilities �?seamless ytterbium substitution, solid absorption attributes, ultrashort pulse era and performance in Power conversion �?positions the Yb:KYW crystal for a cornerstone within the laser technological know-how, masking various fields starting from scientific research to industrial applications.
The comparison with Eyeglasses is suitable Because the large gain bandwidth permits e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
time. Crystals in the compound melts congruently at 1007 oC, nevertheless melt crystallization of high quality crystal is difficult resulting from stage changeover at ~920 oC. The very best seeded Alternative method from
Shade-coded reflectivity of the Bragg mirror as being a operate of wavelength and angle of your incident beam.
Optical structure of the laser with immediate pumping with the radiation of semiconductor injection lasers. LD is surely an IPG Photonics laser diode with fiber output with the radiation, WP is usually a half-wave plate, CL is usually a collimating lens, FL is a focusing lens, AE is undoubtedly an Energetic component created from an Yb:KYW crystal, DM is really a spherical dichroic mirror, M1-M6 are definitely the cavity mirrors, OC may be the output mirror, and SAM is often a semiconductor saturable-absorber mirror.
The monoclinic crystal buildings brings about a natural birefringence, helping to prevent thermally induced polarization rotation and depolarization loss.
Raman, luminescence and transmission spectra reveal optical capabilities owing into the existence of thulium ions, and as a consequence the materials could possibly be more researched while in the scope of laser and luminescence apps.
A large brightnessQ-switched oscillator and regenerative amplifier determined by a twin-crystal Yb:KGW laser
... at 50 %-peak ended up produced inside a learn oscillator with selfsynchronization of your axial modes, described in our earlier post. 21 The new edition on the laser, unlike that explained inside our before post, made use of more info an Yb:KYW crystal by having an N pcut (optical axis N p with the index ellipsoid was parallel towards the propagation route from the laser radiation), With all the polarization from the produced radiation directed along the N m axis.
Higher-electricity repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical purposes

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

Simultaneously, a shorter laser wavelength is usually obtained; it is possible to operate by using a quantum defect very well down below one%. As a consequence, the heat generation may be so tiny that this partly compensates the decreased thermal conductivity.
