The acquire bandwidth e.g. of Yb:KGW and Yb:KYW is extremely huge in comparison with that of Yb:YAG. This enables for vast wavelength tunability and for Significantly shorter pulse durations from mode-locked lasers. Values effectively beneath 100 fs have already been accomplished with passive mode locking.
This exclusive attribute of ultrafast pulses permits nonlinear optical conversation with tissue at low General exposure, and drives programs including deep-tissue multiphoton microscopy and substantial-precision eye operation
time. Crystals on the compound melts congruently at 1007 oC, even so melt crystallization of high quality crystal is difficult on account of period transition at ~920 oC. The top seeded Resolution technique from
Colour-coded reflectivity of a Bragg mirror to be a functionality of wavelength and angle of your incident beam.
Optical structure of a laser with immediate pumping Using the radiation of semiconductor injection lasers. LD is definitely an IPG Photonics laser diode with fiber output of the radiation, WP is actually a 50 %-wave plate, CL is actually a collimating lens, FL is actually a concentrating lens, AE can be an Lively ingredient created from an Yb:KYW crystal, DM can be a spherical dichroic mirror, M1-M6 are the cavity mirrors, OC could be the output mirror, and SAM is usually a semiconductor saturable-absorber click here mirror.
The monoclinic crystal buildings brings about a natural birefringence, helping to avoid thermally induced polarization rotation and depolarization decline.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and therefore are utilised as lasing elements to crank out ultrashort (~ one hundred-two hundred fs) substantial electricity pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact laser methods.
Spatial structure from the beam plus the corresponding depth profiles I for the output with the laser.
EKSMA Optics utilizes cookies to provde the ideal buying working experience. In case you continue to implement our providers, We're going to suppose that you just conform to the use of these kinds of cookies.
Substantial-electric power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical purposes

Li2WO4-WO3 flux was productively used lessening The expansion temperature underneath 900 oC. In line with solitary crystal x-ray measurements, the crystal corresponds towards the P2/n House group.
Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison with its counterpart Yb:KGW, is really a outstanding content that performs a vital role in laser engineering. Its primary operate will be to deliver ultrashort pulses of light, spanning just some hundred femtoseconds.
Ask RP Photonics for any tips about tungstate lasers, which include femtosecond lasers and higher-electrical power lasers.
