Micro-Photoluminescence setup:

The above image shows the micro-photoluminescence setup in our lab ' nanophotonics'. There are two different types of cryostats (see below), where the samples could be cooled down as low as 2.2 K. 

Lasers:

The following lasers are there in nanophotonics lab:

• Millennia CW laser (6W), 532 nm
• 3900s tunable Ti:Sapphire laser, 700-1000nm
• Tsunami modelocked laser

Cryostats:

                                            Attocube cryostat   

                                                            Janis cryostat

• High spectral resolution: ~0.12 nm
• Broad spectral  range (300 - 1700 nm)
