HL6343G/44G Circular Beam Low Operating Current ADE-208-1528 (Z) Preliminary Rev.0 May 2002 Description The HL6343G/44G are 0.63 µm band AlGaInP laser diodes can be operated with low operating current. These products were designed by self aligned refractive index (SRI) active layer structure. These are suitable as a light source for laser levelers, laser scanners and optical equipment for measurement. Application • Laser leveler • Laser scanner • Measurement Features • Optical output power : 10 mW CW • Visible light output : 635 nm Typ • Low operating current : 35 mA Typ • Low aspect ratio : 1.2 Typ (almost circular beam) • Operating temperature : +50°C • TM mode oscillation Internal Circuit • HL6344G Internal Circuit • HL6343G Package Type • HL6343G/44G: G2 1 1 3 PD LD 2 3 PD LD 2 HL6343G/44G Absolute Maximum Ratings (TC = 25°C) Item Symbol Value Unit Optical output power PO 10 mW Pulse optical output power PO(Pulse) 12 * mW LD reverse voltage VR(LD) 2 V PD reverse voltage VR(PD) 30 V Operating temperature Topr –10 to +50 °C Storage temperature Tstg –40 to +85 °C Note: Pulse condition : Pulse width ≤ 1 µs, duty = 50% Optical and Electrical Characteristics (TC = 25°C) Item Symbol Min Typ Max Unit Test Condition Optical output power PO 10 — — mW Kink free Threshold current Ith — 20 30 mA Slope efficiency ηs — 0.8 — mW/mA 6 (mW) / (I(8mW) – I(2mW)) Operating current IOP — 35 45 mA PO = 10 mW Operating voltage VOP — 2.4 2.7 V PO = 10 mW Lasing wavelength λp 630 635 640 nm PO = 10 mW Beam divergence parallel to the junction θ// — 17 25 deg.
