This exclusive characteristic of ultrafast pulses enables nonlinear optical interaction with tissue at very low Total publicity, and drives applications such as deep-tissue multiphoton microscopy and significant-precision eye surgery
We current a twin-crystal Yb:KGW laserthat iscapable to work as a Q-switched oscillator with output electrical power approximately 24 W and pulse duration of twenty ns,or to be a regenerative amplifier with output power up to 21 W and pulse duration below 200 fs following compression of chirped pulses. Both equally lasers have fantastic beam high-quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Screen solid peaks at 980 nm and 1030 nm, respectively, making sure effective Strength conversion and significant overall performance in laser techniques.
By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW mainly because of the comparable sizes of such chemical things nearly 100% of Yb-doping might be realized. This special attribute permits ytterbium to take the position of yttrium with virtually no disruption to the crystal’s lattice.
Following air drying and subsequent cleaning which has a cotton cloth soaked in alcohol, the film area showed no indications of peeling or scratches.
Raman, luminescence and transmission spectra reveal optical capabilities owing to the presence of thulium ions, and so the materials may be further studied in the scope of laser and luminescence applications.
Spatial framework from the beam as well as the corresponding intensity profiles I with the output on the laser.

By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW a result of the related sizes of these chemical factors up to one hundred% of Yb-doping could possibly be accomplished.

Li2WO4-WO3 flux was productively used decreasing the growth temperature down below 900 oC. Based on solitary crystal x-ray measurements, the crystal corresponds for the P2/n space team.

Simultaneously, a shorter laser wavelength is often acquired; it can be done to operate which has a quantum defect properly below one%. As a consequence, the heat technology may be so compact that this partly compensates the decrease thermal conductivity.
