“…At an injection current of 9 A, this device yielded near diffraction limited, narrow bandwidth cw emission with optical output powers of up to 5.5 W at a wavelength of 1064 nm. For single pass SHG, they used a PPLN crystal with a planar waveguide (150 3 μm 2 ) and 18 mm interaction length [137]. By using four crossed cylindrical lenses, they were able to couple about 20% of the power of the fundamental light into the waveguide.…”

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).

“…high power, good beam quality and narrow spectral linewidth [8][9][10][11]. Frequency doubling of such lasers has been demonstrated at different wavelength regions [12][13][14][15]. Recently, single-pass SHG of tapered diode lasers with an embedded distributed Bragg reflector (DBR) has resulted in more than 1.5 W of visible light at 488 nm and 532 nm and in a cascade of two nonlinear crystals as much as 3.5 W was demonstrated [16].…”

“…In recent years, planar waveguides for SHG have been investigated because of the advantages of one-dimensional confinement in comparison to bulk crystals. In addition, planar waveguides are attractive for coupling with tapered lasers because they enable one-dimensional beam-size scaling [10]. SHG in an experimental setup of an MgO: periodically poled lithium niobate (PPLN) setup using a planar waveguide with a masteroscillator power-amplifier (MOPA) [10] and a DBR tapered laser diode [11] as pump source with bulk crystal were utilized for high-power blue light generation.…”

We demonstrate a continuous-wave 460-nm compact visible laser module having a footprint of 75 mm × 25 mm × 25 mm. This blue light source is achieved through single-pass second harmonic generation with a distributed Bragg reflector tapered diode laser as a single-frequency pump source at ∼920 nm in a periodically poled MgO-doped lithium niobate crystal with a planar waveguide. The compact blue laser module reached an optical output power of 286 mW with the highest optical conversion efficiency of 11.6% at room temperature. The power stability of the blue light from the laser module is measured at an output power of 268 mW with a variation of ±3.5% during a period of 1 h.
