Making use of our advertising and marketing package deal, you could Exhibit your symbol, further more beneath your item description, and these will been witnessed by several photonics professionals.
This exclusive characteristic of ultrafast pulses permits nonlinear optical interaction with tissue at reduced General publicity, and drives applications which include deep-tissue multiphoton microscopy and superior-precision eye surgical procedure
Femtosecond laser depending on Yb:KYW crystals with suppression of spectral narrowing inside a regenerative amplifier by spectral profiling of the heartbeat
Color-coded reflectivity of a Bragg mirror for a functionality of wavelength and angle from the incident beam.
Optical structure of the laser with immediate pumping Along with the radiation of semiconductor injection lasers. LD is really an IPG Photonics laser diode with fiber output of the radiation, WP can be a 50 percent-wave plate, CL can be a collimating lens, FL can be a focusing lens, AE is undoubtedly an active aspect created from an Yb:KYW crystal, DM is actually a spherical dichroic mirror, M1-M6 are classified as the cavity mirrors, OC would be the output mirror, and SAM is actually a semiconductor saturable-absorber mirror.
The monoclinic crystal buildings results in a all-natural birefringence, helping to keep away from thermally induced polarization rotation and depolarization reduction.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and are employed as lasing resources to make ultrashort (~ one hundred-two hundred fs) substantial electric power pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes operating at 981 nm supports compact laser systems.
Spatial composition of your beam and the corresponding depth profiles I within the output of your laser.
EKSMA Optics makes use of cookies to give you the most effective purchasing encounter. If you proceed to work with our solutions, We'll think that you just conform to the usage of such cookies.
By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW a result of the identical sizes of those chemical factors approximately a hundred% of Yb-doping could be obtained.
The thermal conductivity of frequent double tungstates is from the order to three–4 W/(K m) �?which is not undesirable in comparison with other laser crystals (Despite the fact that a number of occasions under for YAG), and pretty large when compared with the thermal conductivity of typical Eyeglasses.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared to its counterpart Yb:KGW, is often a amazing product that performs a very important here job in laser technological know-how. Its Key purpose is usually to create ultrashort pulses of light, spanning just some hundred femtoseconds.
Request RP Photonics for any assistance regarding tungstate lasers, including femtosecond lasers and significant-electrical power lasers.
