Standard Operating Procedure (SOP) Verdi Visible 532nm 5W LASER Located on optical table in Lebow 334, the yellow room. First Time Use 1. Identify location of safety goggles on storage shelf above optics storage drawers (behind optical table) 2. Read Drexel University Laboratory Safety Manual 3. Read operation procedures in Coherent Laser manual, located in same cabinet as AR-ITO glass 4. WRITTEN AUTHORIZATION FROM PROF. FONTECCHIO IS REQUIRED TO OPERATE THE LASER!! Safety Equipment 1. 532nm blocking goggles (orange color) for EVERYONE in room! (No exceptions!) 2. Disposable gloves for complete coverage 3. Lock the yellow room door Safe Exposure Procedure with External Shutter 1. Put on safety equipment as outlined above 2. Make sure everyone in room has on safety goggles 3. Warn everyone that the laser is going to be on and make them aware of the experiment taking place 4. Get laser key from drawer. 5. Insert key in laser and turn to ‘Laser on’ position. Turn on external shutter controller, located next to laser power supply 6. Make sure power level is at 0.01 W (lowest) setting for alignment 7. Open the internal and external shutter and check laser path on optical table, close both when finished checking optical path. 8. Program external shutter timing characteristics, leave cursor on “Time Closed” setting. 9. With both shutters CLOSED, set exposure power via “Set Power 1” or “Set Power 2”. 10. With laser goggles on, press “Shutter Open” on laser power supply to begin 11. Wait until “current” reading on laser power supply is done fluctuating 12. Press “enable” on shutter controller to begin your exposure Safe OFF Procedure 1. Make sure both shutters are closed (Shutter Open light on laser supply is off) 2. Set power to 0.01 W (make sure “Set Power 1” and “Set Power 2” lights are off) 3. Cover optics 4. Turn laser key to ‘Standby’ position and remove key from laser. Turn key in shutter controller to “off” position (Do not remove). 5. Return laser key to glove drawer and fill out information in laser log book 6. Return safety goggles to storage area NOTE: Never turn off main power switch on back of power supply. Senior laboratory personnel following the shutdown procedure in the Coherent Laser manual should only do this. Shutting down the power is very complicated, time consuming, and if done improperly will destroy the lasing crystal at great expense.
