“…This laser system provides desirable characteristics for potential use as a pump for tunable, high-power, narrow-linewidth long-pulse laser systems. Such lasers could in principle be based on optical-parametric oscillators [23][24][25], or on amplification of weaker narrowband cw lasers using gain in media such as titanium:sapphire [26][27][28], dye [29], or nonlinear crystals (via optical parametric amplification). The complete absence of laser spiking in the pump source will minimize the danger of optical damage and provide steady conditions in the pumped medium so as to avoid transient thermal lenses [30,31].…”

A compact frequency-doubled diode-pumped Nd:YAG master-oscillator poweramplifier laser system with programmable microsecond pulse length has been developed. Analog pulse shaping of the output from a single-frequency cw Nd:YAG oscillator, and subsequent amplification, allowed the generation of rectangular pulses with pulse lengths on the order of the Nd:YAG fluorescence lifetime. Rectangular pulses of 1064 nm light with 520 mJ energy, 2.6 kW peak power, and 200 𝜇s duration, with linewidth below 10 kHz, were obtained at a repetition rate of 2 Hz. Second harmonic generation in a LBO crystal yielded pulses of 262 mJ and 1.3 kW peak power at 532 nm. The peak power can be maintained within 2.9% over the duration of the laser pulse, and long-term intensity stability of 1.1% was observed. The 532 nm beam is roughly Gaussian, with 𝑀 2 = 1.41 during the second harmonic generation. This system has potential as a pump source for titanium:sapphire, dye, or optical parametric amplifiers to generate tunable high-power single-frequency radiation.

“…The Ti: sapphire lasers are at present one of the most important tunable laser sources due to its widely tunable operation and good output properties, which are of significant importance in many fields such as nuclear industry, laser spectroscopy, laser chemistry and photolithography [1][2][3][4][5][6] . At present, high power and high pulse-repetition-frequency (PRF) Ti: sapphire lasers are widely studied [7][8][9][10][11][12][13][14][15] . However, due to the severe thermal effects of the Ti: sapphire crystals, the output power and PRF of the Ti: sapphire lasers are limited.…”

“…It is the most widely used crystal for wavelength-tunable laser (Panahi et al, 2015;Wu et al, 2020), and it is a leading material in the field of femtosecond pulse lasers (Kozlov & Samartsev, 2013). The Ti: Al2O3 single crystal with high quality and uniform dopant distribution can be produced as a highpower tunable laser with a range of wavelengths around 600nm to 1100nm (Raeder et al, 2020;Sawada et al, 2017;Zong et al, 2019). A high-quality crystal is required for a tunable solid-state laser.…”

Estimation of Crystallite Size, Density, and Compositional of the Ti: Al2O3 Single Crystal

The purposes of this research were to estimate the crystallite size, density, and chemical composition of the ingot Ti: Al2O3 crystal grown by the Czochralski method. The crystallite size and composition of Ti: Al2O3 crystals had been determined using x-ray diffraction (XRD) and energy-dispersive x-ray spectroscopy (EDXS). Based on the Archimedes principle, the density of the crystals had been determined. The XRD patterns showed a single central peak with high intensity for all samples. It indicated that all samples had a single crystal. The average value of the samples' crystallite size was in the range of 20.798 nm to 34.294 nm. The ingot crystal density and Ti composition increased from the top to the bottom part because the solid solution was distributed unevenly during the growth process.
