The achieve bandwidth e.g. of Yb:KGW and Yb:KYW is quite substantial in contrast with that of Yb:YAG. This enables for huge wavelength tunability and for much shorter pulse durations from manner-locked lasers. Values nicely under one hundred fs are already accomplished with passive method locking.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared with its counterpart Yb:KGW, is actually a amazing materials that performs an essential purpose in laser technologies. Its Major operate should be to deliver ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
We present a twin-crystal Yb:KGW laserthat iscapable to operate as a Q-switched oscillator with output electricity nearly 24 W and pulse length of twenty ns,or as being a regenerative amplifier with output ability nearly 21 W and pulse duration beneath 200 fs right after compression of chirped pulses. Both of those lasers have excellent beam top quality with beam parameter M2
FIG. 4. Autocorrelation function of the heartbeat 共a兲and spectrum 共b兲of a laser with a rectangular Lively factor for an output ability of 700 mW. The width of
Optical format of a laser with direct pumping With all the radiation of semiconductor injection lasers. LD is surely an IPG Photonics laser diode with fiber output of your radiation, WP is actually a 50 %-wave plate, CL is usually a collimating lens, FL is really a concentrating lens, AE is undoubtedly an Lively ingredient made out of an Yb:KYW crystal, DM is usually a spherical dichroic mirror, M1-M6 tend to be the cavity mirrors, OC would be the output mirror, and SAM is usually a semiconductor saturable-absorber mirror.
Adhesion Test Compliant with MIL-C-675C armed service criteria, an adhesion exam concerned making use of a tape that meets LT-90 specs on to the lens movie layer. The tape was affixed completely and then eradicated vertically. This process was performed thrice, resulting in no blistering or peeling.

Spatial composition in the beam along with the corresponding depth profiles I for the output with the laser.

By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW because of the identical dimensions of those chemical elements up to 100% of Yb-doping may very well be accomplished.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) as compared to its counterpart Yb:KGW, can be a amazing material that performs a vital purpose in laser technologies. Its Main operate is always to deliver ultrashort pulses of light, spanning only a few hundred femtoseconds.
Request RP Photonics for almost any guidance relating to tungstate lasers, which include femtosecond lasers and substantial-electrical power lasers.
