The most repetition level continues to be determined by the maximum repetition rate with the intracavity EO modulator (Computer system) utilized for seeding in and extracting pulses with the amplifier. The Laptop repetition is limited via the damping charge in the oscillations inside the crystal birefringence that crop up with the excitation of For each from the crystal. The For each is generated from the piezoelectric impact and can be quantified utilizing the piezoelectric continuous related to crystal composition and ferroelectric domains. For each of KDP and KTP were captured at high voltage from ten kHz to 200 kHz are illustrated in Fig.

Experts and engineers working with crystals of KTP household are invited to contribute to The difficulty.
Many metals mirror the 1.06 micron radiation of significant electrical power Nd:YAG lasers, yet take up the frequency doubled eco-friendly light-weight, so cutting and welding can be achieved efficiently.
For usually paired KTP EO devices, due to the sizeable thermo-optic coefficient of the KTP crystal, and the several Vitality of the oscillating laser and pumping gentle absorbed by the back and front crystals, the thermal depolarization result will happen beneath the condition of significant pumping depth, which can bring on the deterioration of dynamic extinction ratio, the rise of insertion decline and the reduce of switching functionality.

11a), and one other is to make use of the two crystals orthogonally (Fig. 11b, c). The latter is easily the most employed system for some business products and solutions, whilst our KTP-based mostly EO switch merchandise also hire this design, as proven in Fig. 11d, e. Exclusively, the standard technique of compensating for This really is to utilize a pair of crystals, matched in optical thickness, that's then their utilized electric fields orientated at 90° relative to one another these types of that gentle is polarized alongside the x or y-axis say in the primary crystal is then polarized along the z-axis of the 2nd crystal. The “slow�?ray in the first crystal then results in being the “rapid�?ray in the second and the overall static birefringence is Hence in concept canceled while in the composite crystal pair.
It really is used in surgical lasers, in which selective absorption makes it possible for clinical ablation when averting damage to adjacent tissue. Extra especially, the eco-friendly mild made KTP Crystal by KTP is employed for executing some kinds of prostate surgeries.
KTP will be the mostly used substance for frequency doubling of Nd:YAG lasers and various Nd-doped lasers, notably within the reduced or medium electricity density. The subsequent desk lists the major NLO Qualities of KTP for frequency-doubling of the Nd:YAG laser.
If the KTP crystal is employed as an EO modulator, the applied electric powered subject is parallel on the z-axis, and the light propagation way is parallel to your y-axis or x-axis. If a relatively reduced switch-off voltage is wanted, a y-axis switch is necessary. In apply, lengthy x-axis switches in many cases are employed to obtain the desired low switch-off voltage for crystal advancement economics. The E-O coefficient with the H-KTP crystal could be identified as adhere to in Desk three. Our EO coefficient measurement outcomes at 632.8 nm are according to the 1986 take a look at outcomes using the hydrothermal system KTP32.
When operated within a thermally compensated mode, great Q-switching Houses have been shown with KTP crystals in a thermally compensated mode30. Salvestrini et al. have a comparative analyze of 5 nonlinear optical crystals for EO Q-switching of laser resonators. KTP displays the very best values for that EO application’s advantage figures, together with driving voltage, switching pace, and piezoelectric ringing (For each)77. Regrettably, a result of the reasonably large conductivity, when F-KTP was made use of for a substantial regular electric power EO change, electrons injected in the anode of your crystal can decrease the stoichiometric Ti4+ ions within the crystal lattice to Ti3+, although F-KTP developed at temperature continual is used in place of standard the temperature drop flux method78. On applying an electric industry, a black absorbing band moves from the anode to the cathode during the F-KTP, compromising its utility as being a Q-swap. This phenomenon is definitely the electro-chromic hurt pointed out above.
