In functional phrases, the Yb:KYW crystal has located its market in substantial-energy laser programs as a consequence of its capacity to make significant energy ultrashort laser pulses whilst keeping a compact dimensions. The interaction of its functions �?seamless ytterbium substitution, strong absorption characteristics, ultrashort pulse generation and effectiveness in Electrical power conversion �?positions the Yb:KYW crystal as being a cornerstone inside the laser technologies, masking diverse fields starting from scientific investigate to industrial purposes.
The comparison with glasses is suitable since the significant gain bandwidth will allow e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.
We current a dual-crystal Yb:KGW laserthat iscapable to function for a Q-switched oscillator with output power as many as 24 W and pulse size of 20 ns,or as being a regenerative amplifier with output electrical power as many as 21 W and pulse length under 200 fs following compression of chirped pulses. Each lasers have superb beam quality with beam parameter M2
Colour-coded reflectivity of the Bragg mirror to be a purpose of wavelength and angle of the incident beam.
Optical format of a laser with immediate pumping With all the radiation of semiconductor injection lasers. LD is an IPG Photonics laser diode with fiber output in the radiation, WP is really a 50 %-wave plate, CL is really a collimating lens, FL is usually a concentrating lens, AE is definitely an Lively component made from an Yb:KYW crystal, DM can be a spherical dichroic mirror, M1-M6 would be the cavity mirrors, OC could be the output mirror, and SAM is really a semiconductor saturable-absorber mirror.
Adhesion Check Compliant with MIL-C-675C navy benchmarks, an adhesion test involved applying a tape that meets LT-90 specs onto the lens film layer. The tape was affixed absolutely and after that taken out vertically. This procedure was executed thrice, causing no blistering or peeling.

A superior brightnessQ-switched oscillator and regenerative amplifier according to a dual-crystal Yb:KGW laser
For tungstates, read more the ytterbium doping focus can be extremely high with no sizeable quenching as the replaced ions have a really related ion radius, as well as inter-ion length is pretty significant.
Substantial-power repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical purposes
Though ytterbium-doped laser acquire media normally exhibit a little quantum defect, ytterbium-doped tungstates permit for significantly little values. As an example, a 1030-nm Yb:YAG laser would Typically be pumped close to 940 nm, whereas Yb:KGW or Yb:KYW could be most competently pumped all-around 981 nm.
Li2WO4-WO3 flux was correctly applied minimizing The expansion temperature below 900 oC. In line with one crystal x-ray measurements, the crystal corresponds to the P2/n Area group.
Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared with its counterpart Yb:KGW, is usually a extraordinary product that performs a crucial function in laser technologies. Its primary functionality will be to create ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.
Concurrently, a shorter laser wavelength might be received; it is feasible to work that has a quantum defect effectively below one%. As being a consequence, the warmth era can be so modest this partly compensates the decrease thermal conductivity.
