A Simple Key For KYW Crystal Unveiled

In useful conditions, the Yb:KYW crystal has identified its specialized niche in substantial-power laser apps on account of its capacity to make significant Electrical power ultrashort laser pulses while maintaining a compact measurement. The interaction of its attributes �?seamless ytterbium substitution, solid absorption characteristics, ultrashort pulse generation and performance in Electricity conversion �?positions the Yb:KYW crystal as being a cornerstone within the laser technology, masking various fields ranging from scientific exploration to industrial programs.

This paper describes a femtosecond laser regenerative amplifier dependant on two Yb:KYW crystals with immediate longitudinal pumping by strong linear arrays of semiconductor injection lasers having fiber output. To avoid spectral narrowing all through amplification and the corresponding lengthening on the amplified pulse when it can be compressed, a combination of two Yb:KYW crystals ended up employed, with the spectral maxima in the amplification shifted relative to one another and with spectral profiling on the amplified radiation.

Before the event of Nd:YAG, Nd3+:CaWO4 was a vital unusual-earth-doped laser get medium. It was in truth used in the main constantly operating crystal laser.

By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW due to the comparable dimensions of these chemical features up to 100% of Yb-doping could possibly be reached.

The thermal conductivity of popular double tungstates is of your buy to 3–4 W/(K m) �?which isn't lousy as opposed with other laser crystals (Whilst various moments under for YAG), and fairly massive compared with the thermal conductivity of usual glasses.

Li2WO4-WO3 flux was efficiently applied lessening the growth temperature down below 900 oC. In keeping with solitary crystal x-ray measurements, the crystal corresponds towards the P2/n Room group.

Concurrently, a shorter laser wavelength could be attained; it is feasible to operate using a quantum defect well beneath 1%. Being a consequence, the heat era is usually so smaller that this partly compensates the lower thermal conductivity.
