We present a dual-crystal Yb:KGW laserthat iscapable to operate for a Q-switched oscillator with output power up to 24 W and pulse duration of 20 ns,or like a regenerative amplifier with output electrical power up to 21 W and pulse period beneath two hundred fs right after compression of chirped pulses. Both of those lasers have great beam excellent with beam parameter M2
In case you are seeking to entry This great site applying an nameless Non-public/Proxy community, please disable that and take a look at accessing web site once again.
By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW due to the comparable dimensions of these chemical features approximately one hundred% of Yb-doping may be realized. This unique characteristic permits ytterbium to go ahead and take position of yttrium with almost no disruption to the crystal’s lattice.
Adhesion Test Compliant with MIL-C-675C military services expectations, an adhesion test concerned implementing a tape that fulfills LT-ninety technical specs onto the lens film layer. The tape was affixed absolutely and after that eliminated vertically. This method was done three times, resulting in no blistering or peeling.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and they are used as lasing components to crank out ultrashort (~ 100-two hundred fs) higher energy pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes functioning at 981 nm supports compact laser devices.
Spatial construction in the more info beam plus the corresponding depth profiles I within the output of the laser.

... Not simply the place of crystal while in the cavity and also the amplification axis of crystal influences the laser operation considerably, as the absorption and emission cross sections on the crystal are very unique based on the orientation on the crystal.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) as compared to its counterpart Yb:KGW, can be a impressive substance that performs a very important function in laser technological innovation. Its Major operate is usually to produce ultrashort pulses of light, spanning just a few hundred femtoseconds.
