The attain bandwidth e.g. of Yb:KGW and Yb:KYW is rather big in comparison with that of Yb:YAG. This permits for wide wavelength tunability and for A great deal shorter pulse durations from mode-locked lasers. Values effectively below 100 fs are actually accomplished with passive method locking.
The comparison with glasses is suitable Considering that the significant attain bandwidth permits e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
time. Crystals of the compound melts congruently at 1007 oC, however soften crystallization of top of the range crystal is impossible as a result of period changeover at ~920 oC. The highest seeded Alternative process from
The absorption and emission spectra of Yb:KYW Crystals Show sturdy peaks at 980 nm and 1030 nm, respectively, making sure productive Strength conversion and large effectiveness in laser systems.
Optical format of the laser with immediate pumping with the radiation of semiconductor injection lasers. LD is undoubtedly an IPG Photonics laser diode with fiber output from the radiation, WP is really a 50 percent-wave plate, CL is often a collimating lens, FL is usually a focusing lens, AE can be an Lively component made from an Yb:KYW crystal, DM is really a spherical dichroic mirror, M1-M6 are the cavity mirrors, OC will be the output mirror, and SAM is really a semiconductor saturable-absorber mirror.
Just after air drying and subsequent cleansing which has a cotton fabric soaked in Liquor, the movie floor confirmed no signs of peeling or scratches.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and so are made use of as lasing materials to deliver ultrashort (~ 100-two hundred fs) significant energy pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes running at 981 nm supports compact laser systems.
Spatial structure with the beam plus the corresponding depth profiles I for the output of your laser.

By substituting yttrium with ytterbium within the crystal lattice of Yb:KYW due to identical dimensions of such chemical aspects approximately one hundred% of Yb-doping may very well be achieved.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared with its counterpart Yb:KGW, can be a exceptional substance that performs an essential purpose in laser technologies. read more Its Key perform would be to create ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.
Inquire RP Photonics for just about any tips relating to tungstate lasers, which include femtosecond lasers and superior-ability lasers.
