The attain bandwidth e.g. of Yb:KGW and Yb:KYW is rather massive when compared with that of Yb:YAG. This allows for extensive wavelength tunability and for A great deal shorter pulse durations from method-locked lasers. Values well down below a hundred fs happen to be realized with passive manner locking.
The comparison with Eyeglasses is acceptable Because the significant obtain bandwidth makes it possible for e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
We existing a dual-crystal Yb:KGW laserthat iscapable to function being a Q-switched oscillator with output electrical power up to 24 W and pulse duration of 20 ns,or as being a regenerative amplifier with output power as many as 21 W and pulse length below 200 fs after compression of chirped pulses. Equally lasers have superb beam high-quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Display screen solid peaks at 980 nm and 1030 nm, respectively, guaranteeing economical Power conversion and large overall performance in laser programs.
This paper describes a femtosecond laser regenerative amplifier according to two Yb:KYW crystals with immediate longitudinal pumping by effective linear arrays of semiconductor injection lasers having fiber output. To forestall spectral narrowing in the course of amplification as well as corresponding lengthening on the amplified pulse when it is compressed, a mix of two Yb:KYW crystals have been used, While using the spectral maxima on the amplification shifted relative to each other and with spectral profiling of the amplified radiation.
Adhesion Test Compliant with MIL-C-675C armed forces criteria, an adhesion test involved applying a tape that fulfills LT-90 requirements on to the lens movie layer. The tape was affixed absolutely then taken off vertically. This course of action was performed thrice, leading to no blistering or peeling.
Raman, luminescence and transmission spectra expose optical characteristics owing to website your existence of thulium ions, and for that reason the resources might be further more examined during the scope of laser and luminescence purposes.
Tungstates are likely to acquire large Raman coefficients (�?Raman scattering). Consequently, they can make substantial Raman attain at moderate optical intensities. It is feasible to utilize the laser crystal alone being a Raman converter.
