OSRAM Opto Semiconductors

The SPL LL90_3 is a hybrid laser module. Additional to the laser chip the module contains two capacitors and a MOSFET which act as a driver stage. The two capacitors are connected in parallel to sum their individual capacitance of 47 nF. The emission wavelength is 905 nm. The specified optical peak power is 70 W.

To operate the SPL LL90_3 two DC voltages are needed namely the supply voltage Vs (e.g. 15 V) for the MOSFET driver IC and the charge voltage Vc (e.g. 18.5 V) for charging the capacitors. Please note that the charging resistor determines the charging current and therefore the time necessary to charge the capacitors i.e. the maximum lasing repetition rate.
