The laser employs a V-cavity geometry with a gain chip at the end of one cavity arm and a lithium triborate (LBO) crystal for second harmonic generation. The gain chip has a bottom-emitting design with ten GaInAs quantum wells of 7 nm thickness, which are strain compensated by GaAsP. The system is capable of producing up to 2.4\u00b1 0.1W (total power in two separate output beams) in the visible. The free-running relative intensity noise was measured to be below \u221255 dBc\/Hz over all frequencies from 1Hz to 1MHz. With acoustic isolation and temperature regulation of the laser breadboard, the mode-hop free operation time is typically over 5 hrs. To improve the long-term frequency stability, the laser can be locked to a Doppler-free transition of molecular iodine. To estimate the short-term linewidth, the laser was tuned to the resonance of a reference cavity. From analysis of the on-resonance H\u00e4nsch-Couillaud error signal we infer a linewidth of 50\u00b1 10 kHz. Light at 285 nm is generated with an external build-up cavity containing a \u03b2-barium borate (BBO) crystal. The UV light is used for loading Mg ions in a surface-electrode RF Paul trap. These results demonstrate the applicability and versatility of high-power, single-frequency VECSELs with intracavity harmonic generation for applications in atomic and molecular physics.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"474\" height=\"398\" src=\"https:\/\/beamq.com\/laser\/wp-content\/uploads\/2022\/10\/Single-frequency-571-nm-VECSEL-for-photoionization-of-magnesium.png\" alt=\"\" class=\"wp-image-1034\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"806\" height=\"312\" src=\"https:\/\/beamq.com\/laser\/wp-content\/uploads\/2022\/10\/3-Figure2-1.png\" alt=\"\" class=\"wp-image-1035\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>571nm Laser Color Green Yellow DPSS The 571nm Fiber Coupling Laser has integrated laser diode, laser cavity, fiber coupling optics, power supply, LD current and crystal temperature control in 1.
