UV Laser


Specific instructions and guidance are now on the Communal UV Laser GoogleDoc

The laser is a diode-pumped solid state (DPSS) laser that has been frequency-tripled into the UV range. It uses a galvo and f-theta lens to rapidly pattern areas up to about 8cm^2 with a spot size in the ~15um range, if properly focused. It is good for cutting and marking thin sheets of many materials. By controlling the speed and repetition rate or duty cycle one can ensure ablation of materials without much local melting. Empirical cut parameters for various materials are in the Googledoc listed above.

Location and access

The laser is currently in a room off of MERL129. Access is managed by CDR and requires getting card access via building manager. The laser is delicate and precise, so nobody should be using it without training. The CDR admin is Gosia Wojciechowska. There are several students in BDML and Charm lab who know how to use it properly and can provide informal training.

There is a Google Spreadsheet of trained users. Several of the senior members on this list are good contacts for training new users.

19 July 2022: TonyChen: With Crystal’s help I installed the backup power unit to our UV Laser today, with the UV laser active on + chiller we have approximately 10 minutes before the battery runs out, and much much longer if the UV is not actively on -- which should give us enough time to shut everything down gracefully in case of a long power outage again.

June 24 2022 The UV laser did not suffer damage in this summer's power outage.

July 2021 The UV laser suffered damage in a campus-wide power outage. A new chiller is ordered to repair it.

July 2014: It has arrived and is undergoing its "shakedown cruise." Should be able to make very small (down to 10-15um wide) cuts in a wide range of thin materials (<1mm thick).


A spreadsheet is being maintained to log laser power output to aid diagnostics. The spreadsheet also contains tools to help with temperature tuning.

The user manual, electronic service procedure, and mechanical service procedure are also archived here for convenience. They may also be found from the DPSS Lasers web page.
