3. Place a laser power meter in front of the laser aperture and adjust the temperature control voltage until the maximum output power is achieved Typically a voltage near 3 2 V gives the best performance 4 Trouble Shooting Problem Possible solution The laser does not emit a Make sure the interlock input is closed b Check that the trigger pulses are within the specified range The maximum laser power CW mode remains Make sure the Temp Ctrl input is tied to GND far below the specifications Last change 2015 04 08 Page 7 14 Subject to change without notice 5 Specifications General Specifications Operation mode Wavelength Temperature control input Polarization Polarization extinction ratio Beam divergence FWHM Output beam quality M Pulsed Operation Repetition rate Average power Pulse energy Pulse length Pulse trigger Trigger pulse amplitude Trigger pulse length FWHM Trigger pulse rise time Analog modulation input Continuous Wave CW Operation Output power CW control input pulsed or cw PDL 561 561 2 nm PDL 594 594 2 nm 0 5V horizontal 1 1000 10 5 0 61 1 2 0 100 MHz gt 100 uW 40 MHz 130 uW typ gt 2 5 pJ 3 pJ typ 150 ps 100 ps typ external 2 5V lt 5ns 2ns 0 5V 2 mW 5 mW max 0 10V The PDL must not be operated at output powers above 2 mW for extended periods of time Power Suppl
