DPM crystal- diode-pumped microchip (Glued Laser Microchip crystal Nd:YVO+ KTP)
Parts of green laser installation :
Pumping 808nm diode drawing
Laser diode housing with lens (with AR coating)
laser diode 808nm (case TO5 9mm) 500mW
laser diode housing installed on the 2 axis Adjustable holder
DPM Laser crystal (glued Nd:YVO+ KTP crystal) in the rotating holder (bearing UCP )
Lens is used for focusing green laser beam
PBS – polarising beam splitter cube
adjustable DC-DC power supply for pumping diode and electric motor ( for making pulses )
base laser rail
base aluminum profile 120x40mm, 8mm groove
viewing invisible infrared 808nm beam with sensor card (green on the sensor is reflecting from diodes of power supply)
Setup with beam splitting cube, full power , TEM 00
Successful laser modes on the laser installation
TEM 22
principle of changing lasing modes on the installation is changing the focusing spot of the pumping beam on the crystal input face S1 via rotating of screws on the adjustable laser diode holder
