    OWNERS MANUAL | Cobolt Modulated DPSS Lasers | D0342-C JUNE 2016 Introduction The Cobolt Modulated DPSS option incorporates both the diode pumped laser (DPL) from the Cobolt 04-01 series and an Acousto Optic Modulator (AOM) in one single compact package, slightly longer than the standard 04-01 Series laser head.

  • Page 6: Safety

    OWNERS MANUAL | Cobolt Modulated DPSS Lasers | D0342-C JUNE 2016 Safety General Cobolt Modulated DPSS Lasers are Class IIIB (CDRH), Class 3B (IEC) laser products emit less than 500 mW of laser radiation within the visible spectrum. Residual emissions from the pump diode are contained within the laser head housing via filtering optics.

  • Page 7: Safety Features

  • Page 9: Overview

    OWNERS MANUAL | Cobolt Modulated DPSS Lasers | D0342-C JUNE 2016 Overview In order to modulate the laser, at least one additional modulation source is required, for instance a function generator. The Controller Cable should always be used to connect the Laser Head with the Controller before supplying power to the system.

  • Page 10: Configuration

    OWNERS MANUAL | Cobolt Modulated DPSS Lasers | D0342-C JUNE 2016 Configuration CDRH Compliant The CDRH compliant system is supplied with a key switch on the Controller, which must be connected, along with a remote interlock connector. Once power is supplied, laser radiation starts when the key is turned from the OFF position to the ON position.

  • Page 11: Laser Head

    OWNERS MANUAL | Cobolt Modulated DPSS Lasers | D0342-C JUNE 2016 Laser Head The Laser Head contains a pump diode, laser cavity, beam shaping optics and thermoelectric coolers (TEC) routing optics and an integrated AOM. The laser head contains an optical feed-back loop which measures the output power. The Laser Head gets electrical power and control signals from the Controller via a 26-pin HD Sub-D cable.

  • Page 12: Cables

    OWNERS MANUAL | Cobolt Modulated DPSS Lasers | D0342-C JUNE 2016 Cables In the CDRH compliance configurations delivered the standard cables listed below, using any other cable type or length may violate CE compliance. Laser Controller Cable The laser controller cable is a 1m SubD26-SubD26 cable that connects the Laser Head to the Laser Controller. The cable has a minimum bending radius 8 cm.

  • Page 13: Thermal Management

    OWNERS MANUAL | Cobolt Modulated DPSS Lasers | D0342-C JUNE 2016 Thermal Management To ensure operation within given specifications and for the warranty to be valid, the Laser Head must be attached to a heat sink providing adequate thermal resistance. The required thermal resistance for low power models is <0.6 K/W and <0.4 K/W for high power models (i.e.

  • Page 21: Operating Instructions

    OWNERS MANUAL | Cobolt Modulated DPSS Lasers | D0342-C JUNE 2016 Operating Instructions As standard, all lasers are delivered with the Controller set in Auto-start mode. As soon as power is supplied to the Controller the temperature control elements are operating to reach set-point values and the laser emission will start, unless the key-switch is enabled (CDRH model).

  • Page 22: Operating Modes

    OWNERS MANUAL | Cobolt Modulated DPSS Lasers | D0342-C JUNE 2016 Operating Modes There are two operating modes: constant power and constant current. The default mode for Cobolt 04 series lasers when shipped is constant power. In constant power mode the power is monitored on an internal photodiode, and this is used to regulate the current to maintain a constant power level.
