Data Sheet 976nm Laser Module Stabilized with Narrow-Bandwidth Grating LC95A76ULR The Bookham LC95A76ULR single-mode laser module with narrow-bandwidth grating has been designed to provide the stringent noise and bandwidth performance required for second harmonic generation and frequency mixing applications. The laser with narrow-band grating allows high output powers that are very stable with both time and temperature while providing enhanced wavelength and power stability performance. The narrow-bandwidth grating is located in the polarization maintaining fiber pigtail. Features: • >250mW output power • Polarization maintaining single-mode fiber pigtail • Internal thermoelectric heatpump and monitor photodiode • Hermetically sealed 14-pin butterfly package • Spectral width smaller than 100pm • RoHS compliant Applications: • Blue light second-harmonic generation • Frequency mixing 1 Data Sheet Characteristics Conditions unless otherwise stated: Case temperature -20 to +75°C Submount temperature 25°C Monitor diode bias -5 V CW operation Parameter Min Threshold Current (Ith) Typ Max Unit 35 50 mA 700 mA Operating Drive Current (If) Operating Power (Pop) 250 300 Forward Voltage (Vf) mW 1.9 2.5 V 976.0 976.5 nm Spectral Width (FWHM) 35 100 pm Temperature Dependence of Peak Wavelength 7 20 pm/K Peak Wavelength (lp) 975.5 Monitor Detector Responsivity 0.3 µA/mW Monitor Dark Current nA Thermistor Resistance (at 25°C) 9.5 10 10.5 kΩ Intended Laser Submount Operating Temperature 24 25 26 ºC Power Stability (RMS, 100-250mW, 25ºC, 20Hz-2MHz) 0.25 % Heatpump Current (∆T = 50°C, If = 700mA) 1.85 A Heatpump Voltage (∆T = 50°C, If = 700mA) 3 V Polarization Extinction Ratio 13 17 dB Absolute Maximum Ratings Parameter Min Max Unit Operating Temperature -20 75 °C Storage Temperature -40 80 °C Laser Forward Current 800 mA Laser Reverse Voltage 2 V Heatpump Current 2.5 A Heatpump Voltage 3 V 260 °C Lead Soldering Temperature (10s max) 2 100 Fiber Bend Radius 30 mm Data Sheet Fiber Specification Nufern PM980-HP or equivilent 250µm primary coated fiber Connections 3 Pin # Description Pin # Description 1 Peltier cooler (+) 8 Not connected 2 Thermistor 9 Not connected 3 Monitor anode (-) 10 Laser anode (+) 4 Monitor cathode (+) 11 Laser cathode (-) 5 Thermistor 12 Not connected 6 Not connected 13 Case ground 7 Not connected 14 Peltier cooler (-) Data Sheet RoHS Compliance Bookham is fully committed to environment protection and sustainable development and has set in place a comprehensive program for removing polluting and hazardous substances from all of its products.
