We present a dual-crystal Yb:KGW laserthat iscapable to work to be a Q-switched oscillator with output power as much as 24 W and pulse size of twenty ns,or to be a regenerative amplifier with output ability as many as 21 W and pulse length under two hundred fs following compression of chirped pulses. The two lasers have excellent beam high quality with beam parameter M2

FIG. 4. Autocorrelation functionality of the heartbeat 共a兲and spectrum 共b兲of the laser with a rectangular active factor for an output electric power of seven hundred mW. The width of

Optical layout of a laser with immediate pumping Using the radiation of semiconductor injection lasers. LD is really an IPG Photonics laser diode with fiber output of your radiation, WP is really a fifty percent-wave plate, CL can be a collimating lens, FL is usually a concentrating lens, AE is really an Energetic component constructed from an Yb:KYW crystal, DM is really a spherical dichroic mirror, M1-M6 will be the cavity mirrors, OC would be the output mirror, and SAM is a semiconductor saturable-absorber mirror.

The monoclinic crystal structures ends in a pure birefringence, assisting to keep away from thermally induced polarization rotation and depolarization loss.

Spatial framework of your beam plus the corresponding depth profiles I in the output on the laser.

... at 50 %-peak ended up created in a master oscillator with selfsynchronization with the axial modes, explained within our earlier write-up. 21 The new edition from the laser, compared with that explained inside our previously write-up, made use of an Yb:KYW crystal using an N pcut (optical axis N p from the index ellipsoid was parallel into the propagation path of your laser radiation), with the polarization from the produced radiation directed along the N m axis.

By substituting yttrium with ytterbium from check here the crystal lattice of Yb:KYW due to the similar measurements of those chemical elements as many as a hundred% of Yb-doping may be realized.

The thermal conductivity of prevalent double tungstates is of the purchase to 3–4 W/(K m) �?which is not lousy as opposed with other laser crystals (Whilst many times under for YAG), and fairly huge when compared Together with the thermal conductivity of usual glasses.

This tandem of attributes has considerably-reaching implications, particularly in the development of compact yet powerfull lasers.
