“…Intracavity frequency doubling enables highly efficient green emission, but suitable fundamental sources around 1.2 µm for frequency doubling into the yellow range are rare. Hence, the existing frequency doubled yellow lasers are still fairly complex or limited in cw scaling potential . Other nonlinear approaches such as sum frequency mixing, optical parametric oscillators (OPOs), or Raman shifted fundamental sources increase the level of complexity even further.…”

Here, a diode‐pumped laser based on trivalent terbium (Tb3+) as the active ion is reported. Optical pumping of a Tb3+‐doped lithium‐lutetium‐fluoride (LiLuF4) crystal with up to 200 mW from a diode laser emitting at a wavelength of 488.2 nm enables continuous‐wave lasing directly in the green and in the yellow. At an emission wavelength of 542 nm, the laser reaches an output power of up to 43.8 mW with a high slope efficiency of 52% with respect to the absorbed pump power. The yellow laser at 587 nm exhibits a slope efficiency of 22% and the output power of 13.8 mW is only limited by the available pump power. Laser thresholds as low as 14 and 27 mW of absorbed pump power are observed for the green and yellow, respectively. The investigations toward further optimization of the laser performance reveal that highly Tb3+‐doped materials are suitable for compact, efficient, and affordable diode‐pumped solid‐state lasers with direct emission in the visible spectral range. These results are of high relevance, as in particular for the yellow spectral range such systems are currently not available.

“…Wavelength versatility is afforded by wide portfolio of available semiconductor materials 2 , with SDLs having been reported ranging from the UV 5,6 to the mid-IR 7,8 . In order to further engineer these sources to provide the desired laser characteristics, intra-cavity elements can be deployed that allow for single-frequency operation, intracavity frequency conversion or modelocking.…”

ABSTRACTThis paper will present developments in narrow-linewidth semiconductor-disk-laser systems using novel frequencystabilisation schemes for reduced sensitivity to mechanical vibrations, a critical requirement for mobile applications. Narrow-linewidth single-frequency lasers are required for a range of applications including metrology and highresolution spectroscopy. Stabilisation of the laser was achieved using a monolithic fibre-optic ring resonator with free spectral range of 181 MHz and finesse of 52 to act as passive reference cavity for the laser. Such a cavity can operate over a broad wavelength range and is immune to a wide band of vibrational frequency noise due to its monolithic implementation. The frequency noise of the locked system has been measured and compared to typical Fabry-Perotlocked lasers using vibration equipment to simulate harsh environments, and analysed here. Locked linewidths of < 40 kHz have been achieved. These developments offer a portable, narrow-linewidth laser system for harsh environments that can be flexibly designed for a range of applications.

“…Optically-pumped vertical external-cavity surface-emitting lasers (VECSELs) [1] are a rapidly evolving technology which exhibits a wide spectral coverage in an inexpensive and compact setup [2][3][4][5]. Their foundation on semiconductor technology has the major advantage of emission wavelength flexibility which is easily achieved by bandgap engineering.…”

Ultrafast optical parametric oscillator pumped by a vertical external-cavity surface-emitting laser (VECSEL)

et al. 2017

Abstract:We report the first optical parametric oscillator synchronously pumped by a SESAM modelocked vertical external-cavity surface-emitting laser (VECSEL). As a nonlinear medium, we use a periodically poled MgO:PPLN crystal. The VECSEL operates at a wavelength of 982 nm and a repetition rate of 198 MHz. The pump radiation is converted to signal and idler wavelengths tunable in the ranges of 1.4-1.8 µm and 2.2-3.5 μm, respectively, simply by a change of the poling period and crystal temperature. The signal pulses have a duration between 2 ps to 4 ps and an average output power up to 100 mW.
