Compact Orange-Yellow Laser
This series of compact orange-yellow lasers offers two standard wavelengths: 593.5 nm and 561 nm, with engineering samples available at 589 nm or 584 nm. The product line includes both single-longitudinal-mode and low-noise versions, covering output powers of 10 mW, 25 mW, and 50 mW, allowing selection based on different requirements for spectral characteristics, output noise, and power in experimental systems. The series features a compact laser head design, supports free-space output, and offers optional accessories such as beam expansion, fiber coupling, TTL modulation, analog modulation, and a digitally-displayed adjustable-power power supply, facilitating integration into research, inspection, and optical experiment systems.
