We current a twin-crystal Yb:KGW laserthat iscapable to work like a Q-switched oscillator with output electric power as many as 24 W and pulse duration of twenty ns,or being a regenerative amplifier with output electric power as many as 21 W and pulse length under 200 fs following compression of chirped pulses. Both of those lasers have superb beam quality with beam parameter M2
Shade-coded reflectivity of the Bragg mirror as a operate of wavelength and angle of your incident beam.
This paper describes a femtosecond laser regenerative amplifier depending on two Yb:KYW crystals with direct longitudinal pumping by powerful linear arrays of semiconductor injection lasers having fiber output. To circumvent spectral narrowing in the course of amplification along with the corresponding lengthening in the amplified pulse when it is compressed, a mix of two Yb:KYW crystals had been used, with the spectral maxima with the amplification shifted relative to each other and with spectral profiling of your amplified radiation.
Immediately after air drying and subsequent cleaning by using a cotton cloth soaked in Liquor, the movie surface showed no signs of peeling or scratches.
FIG. 1. Optical format of a laser with immediate pumping Using the radiation of semiconductor injection lasers. LD is an IPG Photonics laser diode with fiber output
Tungstates tend to acquire high Raman coefficients (�?Raman scattering). Therefore, they're able to create major Raman acquire at reasonable optical intensities. It is achievable to utilize the laser crystal alone for a Raman converter.
... at 50 percent-peak ended up created inside of a grasp oscillator with selfsynchronization from the axial modes, explained within our previously post. 21 The new version in the laser, not like that explained within our before report, employed an Yb:KYW crystal with the N pcut (optical axis N p of the index ellipsoid was parallel into the propagation route in the laser radiation), With all the polarization with the generated radiation directed alongside the N m axis.
... Not simply the position of crystal from the cavity but will also the amplification axis of crystal impacts the laser operation enormously, since the absorption and emission cross sections on the crystal are quite different based on the orientation with the crystal.
The thermal conductivity of common double tungstates is on the get to 3–4 W/(K m) �?which isn't lousy in comparison with other laser crystals (Though a number of situations lower than for YAG), and quite massive as opposed Together with the thermal conductivity of common Eyeglasses.
Li2WO4-WO3 flux was correctly applied cutting down the growth temperature down below 900 oC. Based on single crystal x-ray measurements, the crystal corresponds on the P2/n House team.
Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared to its counterpart Yb:KGW, is usually a extraordinary product that performs a vital part in laser engineering. Its Most important purpose is usually to click here create ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.
Inquire RP Photonics for virtually any suggestions about tungstate lasers, which include femtosecond lasers and higher-ability lasers.
