4Lasers standard uncoated isosceles dispersing prisms are fabricated from UVFS, BK7, SF11 optical glasses and offer different dispersive properties. Used in both intra- and extra-cavity setups for ultrashort laser pulse temporal manipulation. Their construction enables to use of them at Brewster angle, therefore p-polarized light losses are extremely low.
