“…12b). A DBR M-MOPA delivering narrow bandwidth, diffraction limited emission with an optical output power of more than 2 W was first demonstrated by Parke et al [100]. Recently, more than 10 W of optical output power could be demonstrated with an 8 mm long M-MOPA with 4 mm long tapered and ridge section with two 1 mm long DBR sections [101].…”

A review about second harmonic generation using edge emitting diode lasers and nonlinear crystals to obtain laser radiation in the blue-green spectral range is presented. Therefore, pump laser radiation with high brightness and narrow bandwidth is necessary. Thus, this review gives an overview of the advances made with distributed feedback and Bragg reflector lasers, tapered lasers and amplifiers as well as external cavity diode lasers and master oscillator power amplifier schemes to achieve high brilliance emission. Since periodically poled materials have enabled high second harmonic conversion efficiencies with low and moderate pump powers, the review is focused on frequency doubling using those materials. The most commonly used materials, their properties and limitations are discussed briefly. Single pass and resonant SHG setups with waveguide and bulk nonlinear crystals are discussed and an emphasis on building compact and integrated devices is made. PPLN waveguide crystal pumped by a DFB laser (above). Integrated SHG device on a CCP heatsink (below).

“…The oscillator then feeds a single-pass amplifier. A more prolific form of the integrated MOPA incorporates a tapered amplifier, allowing for the mode to expand in the lateral dimension slowly in order to avoid exciting higher order modes as the light is amplified [66]. Monolithic integration necessitates attending to low mirror reflectivity of a single facet instead of two.…”

“…High power tapered diode lasers with good spectral and spatial quality has become available resulting in a significant reduction of size and complexity compared to MOPA configurations. The spectral selectivity can be done using external cavity approaches [12] or using DFB or DBR gratings within the laser structure [13]. Recently more than 1 W of blue light and more than 1.5 W of green light were generated by single pass frequency doubling of DBR tapered lasers in bulk periodically poled crystals [14,15].…”

We demonstrate the generation of high power (>1.5W) and single-frequency green light by single-pass second harmonic generation of a high power tapered diode laser. The tapered diode laser consists of a DBR grating for wavelength selectivity, a ridge section and a tapered section. The DBR tapered laser emits in excess of 9 W single-frequency output power with a good beam quality. The output from the tapered diode laser is frequency doubled using periodically poled MgO:LiNbO3. We investigate the modulation potential of the green light and improve the modulation depth from 1:4 to 1:50.
