• Large nonlinear optical coefficient (d₃₃ ~27pm/V) – one of the highest available
• Efficient frequency conversion with lower pump power requirements
• Effective doubling from infrared to visible wavelengths

• Ideal for Nd:YAG systems – excellent performance at 1064 nm → 532 nm conversion
• Telecom compatibility – works efficiently with semiconductor lasers at 1.3–1.55 µm
• Broad transparency range (420-5200 nm) allows versatile applications

• Lower material and processing costs compared to premium crystals like RTP
• Good performance-to-price ratio for standard SHG applications
• Accessible entry point for frequency conversion projects

• Mature, well-understood material with established processing techniques
• Reliable performance in conventional laser systems
• Widely supported in the optics community

From their MgO:PPLN products, Raicol offers:

• Periodically poled structures for enhanced quasi-phase matching
• Custom periodicities for specific wavelength requirements
• High-quality crystal growth with controlled domain structures
• Professional optical coatings (AR, DBAR, HR options)

Choose Raicol’s LN for SHG when you need:

• Standard power levels (not extreme high-power)
• Room temperature operation (controlled environments)
• Cost optimization over maximum performance
• Conventional laser wavelengths (especially 1064 nm, telecom bands)
• Established, proven technology rather than cutting-edge solutions

Note: For applications requiring extreme performance, wide temperature ranges, or very high power handling, Raicol would recommend their RTP-based solutions instead, where they hold significant

technological leadership.
