The achieve bandwidth e.g. of Yb:KGW and Yb:KYW may be very massive compared with that of Yb:YAG. This allows for extensive wavelength tunability and for Significantly shorter pulse durations from method-locked lasers. Values well beneath one hundred fs are actually attained with passive manner locking.
The comparison with glasses is appropriate Because the big get bandwidth allows e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
We existing a dual-crystal Yb:KGW laserthat iscapable to operate as being a Q-switched oscillator with output electric power as much as 24 W and pulse size of twenty ns,or as being a regenerative amplifier with output ability as many as 21 W and pulse duration beneath two hundred fs just after compression of chirped pulses. Each lasers have exceptional beam excellent with beam parameter M2

Optical layout of a laser with direct pumping with the radiation of semiconductor injection lasers. LD can be an IPG Photonics laser diode with fiber output on the radiation, WP is often a 50 %-wave plate, CL is really a collimating lens, FL is usually a concentrating lens, AE is surely an Energetic ingredient made out of an Yb:KYW crystal, DM is a spherical dichroic mirror, M1-M6 are classified as the cavity mirrors, OC could be the output mirror, and SAM is usually a semiconductor saturable-absorber mirror.
The monoclinic crystal buildings results in a normal birefringence, assisting to prevent thermally induced polarization rotation and depolarization decline.
FIG. 1. Optical layout of the laser with immediate pumping While using the radiation of semiconductor injection lasers. LD is an IPG Photonics laser diode with fiber output
A superior brightnessQ-switched oscillator and regenerative amplifier based on a dual-crystal Yb:KGW laser

... Not only the situation of crystal inside the cavity but also the amplification axis of crystal impacts the laser Procedure significantly, because the absorption and emission cross sections with the crystal are fairly diverse in accordance with the orientation from the crystal.
