“…The 1.06 μm pulsed laser is an important light source for industrial production, e.g., laser marking [1], laser cutting [2], etc. Moreover, it is also an important fundamental frequency light source in nonlinear optical frequency conversion technology, such as optical parametric oscillator [3], second-harmonic generation [4], stimulated Raman scattering [5][6][7], and third harmonic generation [8]. The pulsed laser achieved by means of actively Q-switched laser has flexible and adjustable pulse repetition frequency, which is crucial for light source in many applications.…”

Combining the respective advantages of Nd:YAG and Nd:YVO 4 crystals in achieving the 1.06-μm band laser, we proposed and demonstrated a highly efficient acousto-optically (AO) Q-switched dual-crystal hybrid gain laser. It not only had excellent power performance but also exhibited satisfactory polarization characteristics across a broad pulse repetition frequencies (PRFs) range. Under 42.00-W incident pump power, the maximum average output powers were 12.10 W and 19.64 W at the PRFs of 10 kHz and 200 kHz, respectively. The corresponding optical-to-optical efficiency rose from 28.81% to 46.76%. The results were significantly better than those of the conventional single-crystal laser in our control experiments. The laser polarization ratios at maximum average output power were ~7.6:1 and ~11:1 when the PRFs were 10 kHz and 200 kHz, respectively.

“…Green lasers have attracted a lot of attention for use in numerous promising applications. Armarium [1][2][3][4][5] is one such application, used in prostate surgery to removing prostatic tissue. 1) 532 nm laser light can eliminate prostatic tissue which can highly and selectively absorb the laser and can result in thermal energy.…”

“…Armarium [1][2][3][4][5] is one such application, used in prostate surgery to removing prostatic tissue. 1) 532 nm laser light can eliminate prostatic tissue which can highly and selectively absorb the laser and can result in thermal energy. This can release tissue and vapor bubbles to disrupt the cellular matrix, which is the so-called green light photo-selective vaporization of the prostate (green light PVP).…”

Vertical-cavity surface-emitting lasers (VCSELs) are promising in various applications including full-color mobile projectors, laser precision processing, display, armarium and high-speed air-water optical wireless communication systems with a unique combination of advantages. However, GaN-based VCSELs with emission wavelengths in green are challenging because of the low emission efficiency of green emitting InGaN QWs. This is known as the "green gap", which is mainly caused by the quantum-confined Stark effect and the high density of defects and dislocations. In this paper, we would like to discuss the origin of the "green gap" and possible approaches to overcome it, and then review our recent progress in green VCSELs: (1) lasing from 479.6 to 565.7 nm by using QD active area; (2) lasing at 545 nm by using QD-in-QW active structure; (3) lasing at 493 nm by utilizing blue-emitting InGaN QWs with the combination of cavity effect.

“…In recent years, green lasers develop rapidly and have been widely applied in medical treatment, ocean exploration, storage, and so on. [1][2][3][4][5][6] There are three main methods of producing green laser: rare earth ions transition emitting, semiconductor laser directly emitting, and frequency conversion producing. The green lasers emitted by rare earth ions transition have many advantages such as good beam quality and simple structure.…”

Dy3+/Tb3+ co-doped antimony phosphate glasses (PDTs) were prepared by a common melt-quenching method. The spectra properties of PDTs were analyzed in the range of 300 to 850 nm. The sensitization mechanism of Dy3+ in enhancing the visible fluorescence of Tb3+ ions was explored. Since the energy of Dy3+ ions are effectively transferred to Tb3+ ions, an enhancement of Tb3+ emission at 545 nm and a reduction of Dy3+ emission at 575 nm were observed. The energy transfer (ET) between Dy3+ and Tb3+ ions result from the electric dipole interaction. In the PD1T4 sample pumped at 450 nm, a maximum ET efficiency of 63.1% was obtained. The larger values of laser characteristic parameters of Tb3+: 5D4 → 7F5 transition indicate that these antimony phosphate glasses have great potential for green lasing operation.
